Try either GNUCash or Kmymoney

For screenshot, you can use Flameshot which do have a Windows version and even a macOS version:

D101 is definitely my favourite!

Yes, start from Molly v6.31.2-1 it should support linked device.

Molly v6.31.2-1

Your best bet for the time being would be using mollyim-insider-android and that’s what I use on my spare phone (Signal on main phone):

v6.30.4-1+linkdevice.rev10

So far everything works as expected. Good luck!
