It is a most useful extension, i have it on windows and works perfectly, but on android it has some flows: At first, it saves only some of the opened tabs and permanently closes the rest. After some experiments i found out that it does not save the tabs that you have opened in background and not visited, or the tabs that you have not visited after opening the browser. If there is some settings that could fix it, some instructions on this matter from the developers would be very useful. The second annoying thing is that you can not choose whether or not, preferably not but unfortunately not an option, to open the onetab page automatically on a new tab when you open the browser first time after having terminated the app. When the app still runs on the background and you reopen it it does not open the onetab homepage tab. At least i have not found any kind of settings like on the windows version, if someone knows something more please share. If there is a way to overcome these flaws please state it, if not it would be nice to consider fixing them. This is a very useful extension and deserves the perfection, like the windows version..
