Teachers who have been using Doctopus have mentioned that it can get a bit troublesome toggling from tab to tab to provide feedback to students while they work.  The Too Many Tabs extension can help with the clutter.  Too many tabs will convert all of your tabs to a visual group that allows you to see the tab titles and a small view of the content of each tab -- all in one location!

To the left, you see all of the tabs currently open.  On the right are "suspended tabs."  These are tabs that you had open, but that you wanted to save for later.  This keeps them accessible, but doesn't slow down the computer memory.  If you click on a suspended tab, it will reopen.  If you click on the tabs to the left, you will go right to that page.  You can also search the tabs or sort them by name, domain, or creation time.  Suspended tabs can also be searched and sorted.

You can delete suspended tabs at any time, and they will remain there until they are deleted.  So, if you have tabs suspended and you go away for a week, they will still be there when you return.  This could be useful when you have something you want to refer to later, but that you do not want to bookmark.

If you are using Doctopus and you have many students' work opened, you can see the names of the open documents to know which tab belongs to which student's work.  It can certainly help eliminate some confusion while you are trying to work on feedback.

And, if you are like me, you have lots of tabs open all of the time!  This can help you manage them a bit.

To get this extension in the Chrome Store, go to Too Many Tabs.

Tab Scissors and Tab Glue are two very simple extensions that can be quite effective.  Tab Scissors will allow you to take 2 open tabs and quickly divide them into 2 side-by-side windows.  This would be useful when completing research.  For example, if you are gathering information on one website and taking notes in EasyBib, it would separate the two tabs into side-by-side windows allowing you to easily use both pages at once.

Can you do this without an extension?  SURE, but this saves some steps!

Tab Glue puts the two pages back together.  Or if you have two Chrome windows open, tab glue with put them together.

NiftySplit takes the same concept a bit further.  With Nifty Split installed, you can right click on any link on a webpage, and the option "Open as NiftySplit Window" appears.  Selecting that will split the screen with two windows - the link you right-clicked will appear in the right window, and the existing page will remain on the left. Where it gets fancy is that when you navigate in the window on the left side, any link you left click on while in NiftySplit mode will open in the right screen, so you can consistently change what appears on the right screen. Hitting Shift click will open a link in the left window.  Play around with it, and you will see what happens.  Pretty nifty!
