Current problem
Getting a custom CSS theme onto a self-hosted instance currently requires pasting code into a text field with a 32,768 character limit. This is challenging for larger themes, or themes that make extensive use of comments.
Proposed change
The desktop app currently supports uploading or linking to a .css file. Ideally, the web admin page would support this too. This would consolidate the user experience and trade the character limit for a file size limit.
