[Bammede]

if I change some settings, files in dotfiles will they be lost after update? How to preserve them?

Hi. I have pushed today an update to support exactly in this use case.

But you need to run the installer once. So please make a backup with the installer and restore your changes one time.

Then follow the wiki article to protect your changes.
