I only listen to podcasts so you got the big ones: playback speed and remembering position.

Do you intend to support podcasts and audiobooks? Specifically, remembering it stopped playing? If so I will totally drop Finamp for this

Agreed. You need to be willing to migrate to FOSS software or else “switching to Linux” will be a total failure.

I think the key is you need to find FOSS software that works for you before migrating your OS. Most FOSS software will run on windows and sometimes MAC.

1-2 and 3 will be hard. You can find many tools that do something similar but it won’t be perfect. There are a few different music managers, and for office libreoffice is the go to.

4. try digikam, it supports all OSes

5. googling “Fujitsu snap scanner Linux” yielded a few blog articles on the matter. Seems it should be supported.

What’s your goal? Is it safe to match is a very open ended question.

Take RHEL, it’s meant to be a paid distro for enterprise, something Debian isn’t. But you could draw similarities too.

What’s are you trying to learn?

There are tools like rss bridge that can be a big help: https://github.com/RSS-Bridge/rss-bridge

YouTube wise I use invidious rewrite rules

I’m kind of addicted to miniflux.

I use it to aggregate my RSS l, GitHub release notes, & YouTube feeds so I can stay up to date

From what I understand nexcloud isn’t a mail server, only a client. I’d need something that can act as an SMTP bridge to actually send emails.

Proxmox is meant to be an appliance. Meaning, you shouldn’t mess with the base OS .

If you want a desktop it might be better to make a dedicated VM in proxmox for it.

Don’t you need the JRE to run Java code?
