by the way i know DAVx(5) and Nextcloud are FLOSS too, but in order to get contacts synced in WhatsApp I have them installed on my work profile.
here's my app list. on the right the FLOSS profile, on the left the proprietary profile
basically this is a Pixel 3a with GrapheneOS. the default profile only has FLOSS apps, while the work profile has proprietary apps such as twitter, instagram, whatsapp, among others. i have also installed detoxdroid for the grayscale filter.
Krita 5.0 is out! KDE's sophisticated design app for painting, drawing and animating, comes with tons of new features, massive overhauls to key components to make it much faster, and supports more file formats and customized workflows.
Look out for a faster and more flexible Resource System, smoother gradients, faster smudge brushes, a new MyPaint engine, a redesigned animation interface, new and clearer icons, and much, much more.
