PSA: a recently-fixed image parsing vulnerability in Chrome (and things that use Chrome, such as Electron apps) is being actively exploited in the wild. install your updates!
Many/most electron apps don't receive timely security updates, so if you don't want arbitrary images to be able to get code execution you might want to stop using them.
Have you tried Cromite? Its forked from Bromite by one of the original developers, except kept up to date and actively maintained, plus improved constantly, etc.
Can't use it as I have a 32bit phone and the dev refuses to provide a 32bit binary (and won't explain why, referring to some nonexistent past discussion)
