Thank you for this! There is no such thing as small donation, it helps.
But again, it's not my program. I'm just a user. I mostly use it for my character designs.
If you don't digitally paint, Krita probably won't be useful for you. However there are tons of FOSS programs out there. For example LibreOffice might be useful for you and they accept donations as well. If there is something you find useful for yourself, you can throw them a buck once in a while.
If you're new to FOSS community, first of all, welcome. Secondly, you'll find something for your needs hopefully. :)
Thank you!. I donate to them once in a while too. They deserve it.
Heh, you rock too. :)
Also, please pet your kitty for me. <3
Have a great day!
