Your comments

"users like Aaron"?  Tell me what I am like?  I think you are taking my comments a bit too personally.  I do software development that is very user oriented.  Myself and the other's on my team are usually very frank about what the user experience would be like and explore how different changes might improve/degrade a user's experience.  Often times we find solutions that preserve existing behavior for our user base who are used to a certain workflow, and with only slight changes or optional settings, allow other scenarios of usage.  I think what you have is great, but just watching even your videos of what you call intended usage, there are things that a user has to make habitual, when really the software could handle those things for them.  There are a couple sayings "I object to doing something that a computer can do." or DRY:Don't Repeat Yourself, which applies to user experience as much as it applies to software design.  


"99% of the tabs in the tree for heavily tabiters is not saved by them intentionally or organized."   First, let me say you are right that many tabs are temporary, and that my proposal to provide an option to make all tabs saved by default is probably a bit too aggressive, hence my followup post where I have acknowledged that with a alternative solution.  Let's say your statistic is accurate.  When they are intentionally saved or organized that 1%, don't you think that is pretty important?  If someone takes the time to move something out of a window(something temporal) into a group, doesn't that signify something?  Now I have this session that represents some active research I'm doing on a subject so large it encompasses several tabs I've pulled together in a group.  Now I want to take a break from that and switch to another group that involves something else.  I forget to take the extra steps to use the Close&Save button, and instead use the close button of the Window, and that session is lost.  Anytime you have a situation where a user can invest time into something, and then lose everything very easily is not a good situation and will lead to unhappy users.  


"...as with them there bigger stream of good users, who support and help. Of course with them there also a bigger stream of users like Aaron."


Users like me huh? I am programmer/user trying to help something that has a lot of potential, but programmers "like you" see enemies where you have friends.  I would gladly prototype these changes on GitHub because there is alot of value in what you have already, and provide it as a setting such that existing behaviors are preserved, and provide significant improvements for the other "users like Aaron" who leverage and enjoy the organizational features and UI you already have, but get no use out of them because they deplore the fact that they can't easily close a Window and come back to that Window later without having to habitually open another window and find the Save&Close button for that window.  You could easily dismiss user complaints as being your unintended audience, and you will blind yourself to potential improvements.


ln my own career I have often been hired into a lead programmer role on several projects where there was a good number of unhappy users, and I worked with them to determine solutions that were not difficult to implement, preserved satisfaction of already happy users, and addressed the problems of the unhappy users.  All that was really needed was someone to listen to them openly, and the solutions were not difficult to implement.


I will leave it at that.  I will indeed look for another open source solution for which I can indeed "help", since you seem to have already pigeon holed me into some category that you think little of.


If you look at Firefox's default tab manager, closing a Window doesn't clear tabs from a group.  Only closing the tab directly does.  If you are able to discern closing a window from closing a tab, then closing a Window should automatically Save all tabs there so you can restore that window easily later where you left off.

Also thought that this would be the default.  If I take the time to organize tabs into Groups, that implies I have some desire to keep them.  I sit there organizing my tabs, and I close the window thinking "Oh great now I've saved all my tabs into this cool little group and I'll come back later" .... and ... their gone.  If I want to close that window and come back later, I have to always remember to close it via the X in Tab Outliner, and that is only temporary.  There should be a Pin button for groups/pages that makes that item and all children saved such that the only way to delete them is using the Trash icon, and/or an option "All items pinned by default". Otherwise, as soon as I open those again, they will disappear next time if I don't again remember to go back to Tab Outliner.  It only takes one mistake of hitting the X in Chrome and losing everything in my group.  Having to create a note under each and every page is silly IMO.  Is this project open source?
