Why donate?
Since Krita is a KDE application, KDE e.V. sponsors activities like travel to the Libre Graphics Meeting. So, if you donate, what will your money be used for? The community around Krita has in the past donated money to buy hardware -- Wacom tablets -- and to enable Lukas to work full-time for several months. Future plans which will need money are having the Krita manual professionally edited (of course, we need to write it first!) and buying a Wacom airbrush device so we can work on supporting the special features of that too. And we will be looking for more opportunities for sponsored development work of course!
