[Qt-creator] Bookmarks across multiple instances of Qt Creator?

[Schimkowitsch Robert]

Many thanks for the reply!

I'll give the "multiple sessions" one more try. In my first attempt, it removed all the bookmarks from my default session file. I believe, this feature is also not designed with multiple instances in mind.

Also, I actually would prefer my bookmarks to by synced across instances, since I switch branches several times a day. I cannot say that a certain session is attached to a certain branch.
The bookmark I set in session A might become very relevant in session B a few days later, and it's rather tedious search in all bookmarks in all instances.
But I guess this is just not possible at the moment.

Kind regards

Robert
