dialog for edit via has save button not at the bottom by default

Doesn't reproduce on OSX, but I think I know what the fix is for GTK so I'll check it in and we can see.

does not seem to be fixed. If you try to change the size of the dialog you would also notice that the alignment looks a bit odd and you cannot squeeze the dialog as much as expected.

Ahh... that video helped. It does reproduce on Mac; you just have to size the window larger than it needs to be.

(Note that when the window is resized larger you will still see blank space, but it will be above the OK/Cancel rather than below.)

Thanks, OK Button is now correct. The dialog, on the other hand, is still way to big on my system by default.

I also noticed a missing gap between the input field and the visible frame.

For the window title, it would be probably better to call it "Track Properties" / "Via Properties" depending on the selected item

All these have been fixed already in 6.0, but I think we're close enough to the 5.0 end-game that I'd rather not introduce any risk by backporting them.

(I see you're doing your own builds. If you want to see the current 6.0 version you can pull it from https://git.launchpad.net/~jeyjey/kicad/log/?h=6.0. It's nearly a month old but should have the Track/Via Properties stuff in it.)
