I'm just thinking aloud about what would make this valuable enough for me to pay for...

I have several computers with different os's and a phone, that sometimes I call into meetings with, sometimes I use the apps.

I have meetings on teams, zoom, google, webex, (Skype is dead right?)

I may have presentations that I need to give in these meetings, in google docs, ppt, browser tab, etc.

So if your app could unify all of this, so I can click once on whatever device I'm on to get into my meeting, and have my meeting materials at hand, that would be cool.

I'm less big on notifications of any kind, I get too many already, making some new kind of extra important notification won't help.
