True, but "currently vim mode is very broken" and "I am just reporting there are too many vim broken functions to be usable."
That's actually quite a useful feedback because as a non-vim user , I am curious if the functionality I implemented is sufficient for a real vim user or if the plugin is just a toy that is not usable. Now, of course, the second step would be getting more details about what functionality is missing or not working correctly.
And yeah, there are sometimes bug reports that are written in an aggressive tone or are "demanding" a fix and the reporters are hard to deal with but I didn't find anything wrong about this particular bug report. The yank problem was described well in the original post and "I really like to use geany because is fast, but currently vim mode is very broken even with the latest 1.37.1" may well be true for a vim user.
It's alwyas a matter of interpretation what the other person wanted to say but I don't want to discourage people from sending bug reports. And if something is broken, everyone should be allowed to say so. Broken things can get fixed, but first, one has to know they are broken.
