I've only been using this extension for a couple of days, so maybe I did something wrong. I quit chrome, then restarted it a couple of hours later. There are no tabs at all on the Tabs Outliner screen. I have no idea what I did to cause this, so I don't know what to do to fix it. I think I can probably get things going again by uninstalling and reinstalling the extension, but I don't want to reinstall unless I know how to avoid causing this to happen again. 

Can you add a feuature so Tabs Outliner window not go to background when I open tab by mouse third (middle) button in TO?

Opening a window from TO list (including single tabs or entire windows) creates windows that are missing Chrome's URL as shown here:

It should be more like:

I tried several times to purchase a license key from https://sites.fastspring.com/tabsoutliner/ and it doesn't work. The error message also doesn't give a specific reason for it not working. Can you please fix this?

Auto-scroll doesn't work for a default window opened with Chrome start ("Continue where you left off" option is selected). But it does work for every other windows, saved (yellow icon) or default (blue icon).

When I have several Chrome windows open, and I collapse the nodes of all the windows, each window is identified simply as "Window".  This way, I have no way of knowing the contents of each window.  It would be nice if each window could also be identified by the name of the active tab (i.e. the tab in the window that currently has the focus).  This would allow me to easily identify the contents of each window, when all nodes are collapsed.

The tab outliner extension does an incredible job at allowing hierarchical organization of tabs.  Why not leverage this already established structure directly into an real tab functionality which allows the user to collapse/expand the actual chrome tabs either from the header tab itself  (hierarchically) or from the Tabs outliner interface?

To simplify the technical implementation of this, it could be implemented at a high level.  Dummy tabs could be opened representing the root of each hierarchy (the content of each hierarchy would be displayed as a simple hierarchical representation when that Dummy tab is clicked).  If you have 10 roots, you could collapse all and there would be 10 tabs, each representing the respective hierarchies.   Not sure what would be served in terms of speed, efficiency, mem usage and agility when opening/closing a hierarchy of tabs.  

I would highly appreciate the ability to create/modify hotkeys for existing functions in order to operate using custom I/O devices.  Thanks.  (Also someone a couple years ago was mentioning conflicts with other programs...  custom hotkeys are useful)

My tree of tabs is very big.  May be, one button to remove all closed tabs is a good idea.
(I think one button some easy then reinstall the application =D)

On the outliner window, the color of a saved tabs group changes to orange. It would be very helpful if the color of the extension icon also changes when we are in a saved tabs window. This way we would note that any change of window is being saved.
