If you have a bookmarked line (say, line 2) and try to move the next line (line 3) to line 2 using keyboard shortcuts (default: ctrl+shift+up), the previously bookmarked line (now line 3) looses it's highlighting. I actually thought about fixing this myself, but found that a js file would have to be adapted, and the js API doesn't provide access to bookmark information as far as I can see... Reproducible: Always
Right, it's not properly possible right now from js... There are two ways fixing this: Implement this feature in C++ and call from a script, or expose the bookmark API to the scripting interface.
I thought about these options as well, but at least for me this is out of scope, because I don't know anything about the scripting interface or calling c++ functionality from js or js as such. Sorry.
This problem is still present (Kate 20.12.2, KDE Frameworks 5.78.0). (Does the status of the ticket have to be set to CONFIRMED?)
We can set it to confirmed. But at the moment nobody is working on this I am afraid, independent on this setting.
