Can we re-open discussion about this previous feature? I understand it was implemented once but then removed, but I’m not clear on why it was removed.

Merely adding the intended mark to `storedMark` when the caret is at the start of a mark isn’t a fully sufficient solution because the caret is still displayed outside of the mark.

Might a reasonable middleground here be that left-hand inclusiveness is up to the developer, but that when `storedMark` changes at a mark boundary, ProseMirror could check whether the caret needs to move into that adjacent mark?

Thanks for your great work @marijn; interested to hear your thoughts if you have a moment to spare!

For posterity, I hadn’t realized I had already received a reply regarding this here: [Controlling inclusive left/right of MarkTypes - #8 by marijn](https://discuss.prosemirror.net/t/controlling-inclusive-left-right-of-marktypes/267/8)
