in theory there no needs to restore everything if you not  plan to read the tabs content immediately  So my advise - try to restore only the tabs you plan to view immediately. 

Of course i understand that it is easy to say then form such a habit, but you proposal goes against this idea and it will be not implemented. 

Take note that you can restore individual tabs in saved window without restoring everything. 

This feature you ask feels wrong for me. 

I think it is cool to understand what type of people set 1 star rates. Really nice example.

As this is first 1 star review (on 7000 active users) so I think it worth to mentioned full name of the reviewer and review itself there.

So, 1 star review from Chrome Web Store of the same author:

Well it is still not an session-management, and I doubt it will work well after crashes, too.
The reason? Its because of the tab history. Sometimes you want preserve the tab-history, go back and forth. And still this is not possible.
Well its a little better than other ones, but no full fledged session-management.
edit: it even not stores window position and sizes. (importent if you work with different window sets) And its most likely to unintentional delete (closed) tabs without of any chance to restore them.
And the crash restore, unlike the build in one, doesen't use any data from the cache.
It has potential, but still another useless session management alike sort of thing.
And the TabsOutliner tab/window scrolls to much without any reason.
(could fit all into the window, but it scrolls so that only one will be displayed)

Sure, it is planed. I think it will be present in next minor version, in a week or two. Meantime please try configure you monitor. As really i spend many time to ensure it is look adequate enough on all monitors i be able to test. So most likely you have some really weird contrast settings. Maybe for a reason, so of course it must be configurable, and it will be.
