I sometimes struggles to resize windows in Buster/Bullseye/etc.
And I found that EasyOS border thickness, make it easier for me to resize. So, trying to mimic in other distros I use (esp Buster/Bullseye/Bookworm).
I am looking for the setting to change border thickness (not sure what they're called?)
It may also be possible that one can either adjust the thickness or other setting for 'edge' sensitivity. I looked in (and haven't got it yet):
Openbox configuration manager, Customize Look and Feel
I will use screenshots from EasyOS vs Bullseye to show what I mean. I used Firefox as example, but it's any windows really.
