To counter this a bit, I would rather run an Electron app than be greeted with this as the default interface: http://www.qownnotes.org/var/bekerle/storage/images/_aliases...
I'll take an app that uses a bit more resources over something that looks like an IDE instead of a note-taking app any day.
Currently using Inkdrop[0], which is not open source (but subscription based) and has a rather basic Android client, but it's cross-platform (macOS, Windows, Android, iOS, Ubuntu and other Linux-based distributions), has a pretty intuitive interface (as in, doesn't look like an IDE), backs up its database to my Nextcloud instance, and supports dragging and dropping images.
