Not a big issue but I found that some icons in the Chains dialogue can't be themed:
- arrow-up
- arrow-down
- edit-copy
- minus
- plus
I was able to override them using the resources/images folder. However, from looking at 'def get_icon_6_2_plus' in common_utils.py, it looks to me that the icon theme should be prioritized, though it isn't currently being acknowledged, for some reason.
I wanted mainly to theme the 'plus' and 'edit-copy' icons because they look to me a bit faint in dark mode.
The other icons, notably the ones called by Qpushbutton, will change in accordance to the theme images.
I'm running 7.20.101 with the latest plugin version 1.20.7.
