Loving Cloudron! Thank you for this! Having trouble with Git customization though and struggled for many hours today with it ...
Issue summary
Issues with:
1-Successfully load a custom theme
️
2-Successfully load custom templates. ️
3-The app.ini works fine 
when I make an edit and reload Gitea via Cloudron's file manager but I can't get the others two things to go.
My efforts with theme
I tried dropping a CSS file call "theme-gitea-modern.css" and "modern.css" in the custom directory and also both those files in the "custom/public" directory and then I also add the names "modern" and "gitea-modern" at the end of the themes variable inside app.ini so that my app.ini looks like this THEMES = auto,gitea,arc-green,gitea-modern,modern .... just trying to cover all the possibiliies. But it still didn't work.
I am wondering if custom directory is being properly set by Cloudron still? Or maybe I need to chang anything else in app.ini? The Cloudron doc section this is pretty short. Also ...
Efforts with template
- Added some .tmpl files found on github in the custom directory to the custom directory in Cloudron's file manager
- Rebooted Gitea
- Result = Don't see the same html appearing in Gitea HTML output
Where I put the files.
Thank you!
Any input or help is greatly appreciated.
