Had some ideas for this as well (would only work for 'file workers' like programmers) and build something basic using Go to cover all desktops. But then decided those basics are to simple to implement (and therefore copy) to actually make good revenues in the long term.

I also wondered if there really is a market as it is not that difficult and still nobody else seems to do this.

But an idea is just a start of a long process. I am curious how you will price it and what features will be added to make it more unique. Good luck !
