@Yatharth_Agarwal Here are my thoughts.
I like this idea. Basically, having something that did Ctrl + F + Shift + Enter and worked like Ctrl + O (with the ability to search for bookmarks) would be super useful to me. In total we’d end up with three (main) shortcuts (ctrl O and ctrl f), with the third one being something like ctrl+shift+f/o, as Yatharth suggested.
And it could be restricted (don’t know about how on a technical users) to users on pro plans. It would be like Everything by Voidtools for Windows. Super fast and comprehensive. From there, we can use filters like is:document (would exclude the first line or title of each document from results) is:bookmark, is:completed (not implemented yet), etc.
I think that maybe both ctrl+shift+f/o should work for the comprehensive search feature, since it a mix of the two.
