Is your feature request related to a problem? Please describe.
I prefer AppImages and '.deb' packages rather than flatpak.

Describe the solution you'd like
I'd like to be able to use unsnap to automatically remove all snaps from my system and then install the equivalent AppImages or '.deb' packages. I'd be nice to have a fallback system such that if a preferred format isn't available or found, but for another second or third format that package is available, then unsnap would suggest that alternative instead.

Describe alternatives you've considered
Having to manually reinstall everything in another software format; or having to write some kind of script to do that; which feels strange since in my humble opinion unsnap should be capable of doing that.

Bonus
I believe utilities such as AppMan or Pacstall could be helpful to achieve this goal; in addition to, of course, the API of 'apt'.

Thank you for your time and this wonderful software! 🥰
