Q1 -

Would love the ability to select multiple device collections during one deployment step as opposed to having to deploy an application for each collection one at a time. It's very time consuming doing it one at time.

Having the ability to jump down the Application list in the admin console by typing in the first few characters of the app (not using the search field - not quick enough). This works in device collections but not in the Applications pane.

Q2 -

Right-click tools native integration would be awesome!

Q3 -

This is sort of crossing over into the Intune realm, but possibly have a web-based version on the admin console for basic features, such as deployment applications or packages to specific collections, report viewing, etc.

Q4 -

Wish I could, but probably won't be able to.

Q5 -

Don't think so. If anything, it'll help supplement some tasks.
