Hi, I am afraid, I won't be of much help here, but you have been looking at a quite complex problem. I personally don't see myself capable of doing such complex changes that have the ability to cause regressions in other parts of the code.
Also note, that the win_line() function needs to stay in sync with e.g. the chartabsize functions, otherwise the cursor movements get out of sync with the characters displayed on the screen and the cursor may end somewhere else.

Yes, concealing is quite complex and is still not working as expected. Try to click with a mouse at a character where this lines contains concealed characters > 3. So how did you tackle reading the source for the first time? I am old school. I grep around to find interesting places. Sometimes I also just go directly into the debugger. > > 4.

Don't let that scare you away, but you will need a lot of patience to understand possible interactions with different subsystems.
