'''Design question 1'''
What should be the default tab behavior after users close a tab?


Metrics to consider:
===== '''Design question 1:''' What would be the best default tab behavior after users close a tab?  =====
* user actions after close a tab: stay with the tab next to it? or immediately go back to last viewed tab?  how long it takes between "close a tab" and "select the previous tab"?
* if users stay with the tab next to the closed one, what's the relation between them? opened through the same tab? within a same domain? these two tabs are opened next to each other in a very short time?   
* how many tabs are open when users close this tab?
* any add-ons or settings may influence this user behavior?
* considering both mouse action and keyboard action.


In the past, we have observed that people close a tab in different contexts, for example:<br>


'''Design question 2'''
#When people finish using the tab: e.g. users close the tab when finish watching a video. <br>
What should be the default placement when users open a tab through a link in the current tab?
#When people organize browser tabs: e.g. users close some less important or less used tabs when there are too many tabs open in a browser. <br>
#When people temporarily hide a tab: e. g. users close a tab when he detects someone is passing by; he would like to open it again when nobody is watching. <br>


Metrics to consider:
For different contexts, people have different intentions after close a tab, for example:<br>
*user actions after they click a link within a tab (tab A) to open another tab (tab B): any actions before click tab B? If no action happens, how long it takes for people to click tab? if any action happens, how long it takes for each each action?
 
* user behavior around tab B:  
#open another interesting tab<br>
** percentage: move tab B next to tab A (or any other tabs open through tab A)?
#close another less important or less used tab<br>
** percentage: move tab B to other position? (relations between tab B and tabs next to it)
#open whatever tab<br>
** percentage: move tab B and tab A to a new window?
#open the most often used tab<br>
** how many times tab B is moved?
 
* how many tabs are open when users close this tab?
For this test, we would like to to explore what would be the best default browser behavior after users close a tab. We will simply log what users would do after he/she close a tab, and through these log data, we may be able to detect certain patterns that help us design the default browser behavior that meaningful to most users.&nbsp; <u><br></u>
* any add-ons or settings may influence this user behavior?
 
* considering both mouse action and keyboard action.
<u></u>
 
<u>Annotations:</u><br>
 
*T1: the tab user just closed it<br>
*T2: the tab shows automatically after user closed T1<br>
*T3: the tab user selects after T2<br>
 
<br>
 
<u>Metrics to consider: </u><br>
 
*User actions after close T1:&nbsp; T3 - T2=?
*Relations between tabs:&nbsp; relations between T1&amp;T2? relations between T1&amp;T3?&nbsp; relations between T2&amp;T3? (e.g. opened through the same tab? within the same domain? opened at the same time? no relation at all?)  
*Notable charactor for T1,T2 and T3: e.g. most often used? open the longest? previously opened? <br>
 
<br>
 
<u>Generic parameters to log:</u><br>
 
*How many tabs are open in total when users close T1?
*Any add-ons or settings may influence this user behavior?
 
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; * so far 273 add-on is related to tab behaviors based on AMO. <br>
 
*Considering both mouse action and keyboard action <br>
 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; * close the current tab: command+w (Mac); contrl+w (Win) <br>
 
===== '''Design question 2:&nbsp;''' What should be the best default placment when users open a new tab? =====
 
We have observed that people open a tab for different reasons, for example:<br>
 
#Open a new blank tab to type URL or to perform search<br>
#Open a new tab through links within current tab<br>
 
We also notice that people doing following actions after they open a new tab:<br>
 
#drag the newly opened tab next to the previous tab<br>
#drag the newly opened tab next to a particular tab <br>
#drag the newly opened tab to a new window<br>
 
<br>
 
For this test, we would like to explore what we can do to support people open a new tab in a meaningful way.<br>
 
<u></u><br>
 
<u>Annotations:</u><br>
 
Tc: the opening tab before user open Tn (could be Tl or Tr)<br>
 
Tn: the newly opened tab<br>
 
Tl: the tab left to Tn after Tn is dragged <br>
 
Tr: the tab right to Tn after Tn is dragged<br>
 
<br>
 
<u>Metrics to consider: </u>
 
*Type of Tn:&nbsp; with content (opened through a link), or blank?<br>
*User actions after opens Tn when it is blank:&nbsp; how users load content for the newly open blank tab?&nbsp;e.g. type URL, perform search, through other means? After the loading the content, do user perform drag and drop to group Tn with other tabs?<br>
*User actions after open Tn when it is with content: activate Tn immediately? Time between open Tn and activate Tn? do user group Tn with other tabs?<br>
*Relations between tabs: relations between Tc and Tn? relations between Tn and Tl/Tr? '''<br>'''<br>
 
<u>Generic parameters to log:</u>
 
*How many tabs are open when users open and drag Tn?<br>
*Any add-ons or settings may influence this user behavior?
 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; * so far 273 add-on is related to tab behaviors based on AMO.
 
*Considering both mouse action and keyboard action
 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; * open a new blank tab: command+t (Mac); control+t (Win); right click on a tab, through menu button<br>
 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; * open a new tab through a link: command+click (Mac); control+click (Win); right click, setting in Firefox
 
<br>
 
<u>Basic info for this test:</u>
 
*How long the browser is opening for?<br>
*Tab/window amount per person during the browser opening<br>
*How many times Firefox becomes unfocused during the time opening?
*Permanent tab amounts open during the broswer opening. <br>
