Can recommend Symphonium. Costs a few bucks but its very very rich in features

Maybe, havent had the same project on windows. What I had was the need to connect a second monitor/projector, which I can say from experience, was NOT easily done on Linux (I had to mess with stretched monitor, the duplicating didnt work and so on)

An now on a toilet break after trying to fix a permission problem with a local network NAS. I am so fed up with all the (u)mounting, users/groups, chmod/chown and so on, as I am now 3 hours in to it.

Yes, on windows its a trial and error with two ir three checkboxes, done in a few minutes or half an hour. The terminal-knowledge mentionned is definitely a big thing, even with modern distros like Linux Mint I am using right now
