I've addressed these problems you listed in version 0.0.19 but getting updates to the F-Droid store is a very slow process. The next F-Droid release will have auto updates enabled with the F-Droid team, so those and future issues should be fixed relatively quick from that platform.

Regardless, thanks for trying it out.

Edit: feel free to post issues like this directly to the project in github if you decide to try it out again
