EDIT - test experience : killing task Chrome from TaskManager Windows 10 :

--unknown groups of new pages are remembered in TO list f.e. like "Window (crashed Wed Feb 28 2018)"

--named known groups of pages are not duplicated..

Hello Vladyslav, great thanks for your work and please, when you will open your developement for cooperation on, please note me!

Issue of rising number of groups copy with "(crashed...." in name seems may solve this tweak.

It is working for me on actual Chrome on actual Windows 10 (February 2018) :

How to block/disable Chrome popups "restore pages" (https://productforums.google.com/forum/#!topic/chrome/wlE4QvTTmRA)

Many thanks to original author, please test it and read notes :

Accurate directory name is 

"\Users\(actual user name)\AppData\Local\Google\Chrome\User Data\Default"

In file was only single one occurence of "exit_type": "crashed".

Make backup copy, edit and make file read only..

Please write your next experience.

Hi, Vladyslav, please can I disable synchronizing of node's expanding between "cloned view" trees?

Seems widely discussed here "unwanted scroling" to node of active page only, but with your 30000 nodes you might to know the similar behavior of "moving of view", caused by expanding of nodes laying above in the coupled TO window..

Arranging of "source and target" is sometime greately labourious, then I afraid if I could misunderstand to some setting in TO guide/help..
