Hi @Alexey-T,
Start with the next lines:

Put many bookmarks using the core functionality: bookmarks: put bookmarks on carets, selecting many carets previously.

Make a selection that includes at least two bookmarks and delete it:

Cud crash with the remained bookmarks:

I don't see a CRASH here. do you mean app crash? or 'incorrect bookmark postion after'? bookmark pos are correct. you deleted block from line 7, so bookmarks from lines 9/14 are moved to line 7. Two marks -> one mark.
I think will be better delete bookmarks from lines 9/14 when user delete this lines
Yeah exactly I prefer to delete all lines with all content all bookmarks.
I was validating the usage in Intellij-Idea and yes basically when you delete the lines the associated bookmarks also are deleted.

@kvichans asked to make it like this. Rus text in there.
It's handy. I want to keep bookmarks for big block, even if I delete part of text
Hi @Alexey-T
Is possible to give to the user the option of delete all bookmarks or maintain one as now? 馃樃
