A good way to help Krita Devs - Triaging bugs on the bug tracker.
As Krita gets more popular there will be more users and in turn there will be more bug reports. This is a sign of healthy project but as well know Krita is run by volunteers and bug triaging takes a lot of time of the devs.

Bug triaging is checking whether the bug is reproducible or not, asking for information and doing the initial weeding of duplicated bug reports. We users can really help the devs in this department and this will help them save time to actually work on making Krita more awesome.
