Scite looks like a good notepad replacement.

I like the roll-up-when-not-inside feature that is in the ini as an example. I reduced the width of the outside-state caption to a few hundred, instead of the full width, so that you can have them stacked on the left side of the screen, and when you hover, it pops up. I'd like to have the same happen as expected at all screen edges which means that it rolls up instead of down for captions placed on the bottom edge, and on the right edge ... etc.

It's a great feature but I ran into a snag. Is it possible to make it work as you'd expect it to with e.g. Notepad? When you open a Find dialog, the Notepad window underneath, not having the cursor on it, rolls up, which it obviously shouldn't. Can you do "don't roll up if the window is active even if the cursor leaves it but only if clicked outside"? That would make sense.

How do I increase the delay after which it rolls up when the cursor has left the window?

Or you could do it the way I suggested in:

append the font parameters to the file name or save them in a separate file in the same folder. Or even simpler: use the first or last line if it exists. If you use more than one notepad, you have to customize the key commands needed to change the font per app.
