I created a fork of the project to play arround with, the file that need modifications is src/con.c in line 1633.

result = (Rect){border_width, border_width, -(2 * border_width), -(2 * border_width)};

Add a posibility to set in the i3 config file something like

custom_border on
border_top 3
# Default for border_top, border_right, border_left, border_bottom are 0, no need to reasign here ;) 
# in case of custom_border off, keep the same behaviour that actually exists.

I'm not opposed to the idea, but I dislike the syntax proposal. Maybe we could instead extend the border command to take four arguments in which case that's top, left, bottom, right border (similar to CSS). The same for default_border, I guess.

[gabrielpetry]

That could work better, much simpler.

That looks really neat! I'd appreciate it!

Is anyone working on this? Is it something a newcomer could work on?

I'm closing this issue has i3-gaps is being migrated into i3. If this issue still applies, please reopen it in i3.
