better integration with other Products/no Office Online
It would be great if Teams wouldn't neccessarily open everything in the online pendants of its programs. Especially in the desktop version and apps there should be an option to open it in the preinstalled office programs without having to download the files, dig them out, open them and upload them again.
Also a desktop app would be great, the Win10 App is only compatible with ARM chips which aren't yet found in desktop PCs

They support it now! Consider this done. :-) It works great!
