I can open a bunch of tabs and open whichever one I want by double clicking on it. However, once I move a tab to re-order it in the tree, I cannot open that tab anymore from within the TO window. When I double click on it, it simply opens the parent tab. This is frustrating because I reorder my tabs frequently.

I tried closing and reopening chrome. I also tried reinstalling the extension.

The current lineup of the settings window is a mess. There is a total amount of 2 selectable options which consume like 2 pages of text that nobody is willing to read and another 13 options which are "disabled".

I recommend you to outsource the walls of text for the two available options into some kind of a website (the google group should be fine) and make the actual option (the checkbox) as small as possible without missing too much of information. Usually you only need a few words to explain what an option is doing, the other part is just explaination and does not belong to the "settings".

The other options can just be removed. What do I get from seeing them except that these will maybe be implemented at some point in the future? Imo it's totally fine if you just write "More options to come like changing the color, user css costumisation etc."

Useful then googling. Open a lot of pages in "saved" state, and then open pages one by one.

I can't seem to find it. I mean, I don't always reopen all previous tabs and I don't like to go through them every time I start chrome. Maybe put a "delete unopened tabs" button?
