Is your feature request related to a problem? Please describe.
First of all thank you for great WM that I use every day. It helps my orginize things on desktop. I love it, especially in combination with yasb.
I searched issues and discussions but didnt find answer for my question.
Can komorebi have ability to choose border-style. Currently I'm using border width 16 to fill the gaps between border and actual window. If I set smaller width, like 4 or 8 it start showing gaps between window and border.

What Im using - border width 32

I have problem with that - border width 6

Describe the solution you'd like
I want to choose border position style like in Figma or smth (Outside, Inside, Center).
Currently I see it works like Inside border and starts with gap from window. I requesting Outside border style. Dont know about implementation, but border could be behind window and growing outside like in next image.

What I expect to see in komorebi - border width 4 (or 6)

Maybe komorebi have something like that but I missed it in docs and Issues.

I see the technology behind border drawing. Its GDI pen drswing in WM_PAINT callback of the border window, which doesn't have pen alignment property. But in GDI+ you have SetAlignment for pen.
I could implement that, but I need to learn rust an figured out where the GDI+ bindings in windows-rs if they are exists.
Or I have to go even deeper and learn Direct2D or something like that.

I think that you're looking for this command to compensate for the gaps between the border and the window when changing the active window border width:

❯ komorebic active-window-border-offset
Set the offset for the active window border

Usage: komorebic.exe active-window-border-offset <OFFSET>

Arguments:
  <OFFSET>  Desired offset of the active window border

Options:
  -h, --help  Print help

For me the offset option is taking in consideration the window padding so there is still a gap between the actual window and the border.

Hello
You can set negative offset to clear the gaps between window and border. It looks like this:

There is no gaps except the corners of window. Here still some gaps but they are not noticeable.

That's my current config for border

komorebic active-window-border-width 11
komorebic active-window-border-offset -- -3
komorebic active-window-border-colour 66 165 245 --window-kind single
komorebic active-window-border-colour 256 165 66 --window-kind stack
komorebic active-window-border-colour 255 51 153 --window-kind monocle
komorebic active-window-border enable

Idk maybe should close this issue? Because negative offset kind of solves original issue. Just need add some info in docs that you can set negative offset

I was about to create a tutorial video for setting negative offsets today when I noticed that the static config options for setting the border width and offsets unfortunately leak and implementation detail which means that the offset option takes a Rect instead of a signed integer. I'll fix this for the next release, and then it should be possible to set the negative offsets with a single signed integer value directly in the static config file too.

Video of me working on this here: https://www.youtube.com/watch?v=nsJz4KJrBsA

From v0.1.19, in the static config file, border_width and border_offset will be deprecated and users will be directed by the documentation to use active_window_border_width and active_window_border_offset, both of which share the same names as, and take the same arguments as the corresponding komorebic commands!
