could you describe your usual workflow for the tasks you find difficult?
maybe also, what you wish was different to have a easier workflow?
Maybe we can help you find a easier workflow or consider simplifying it in future versions.
I had an awful time handling this at first -- i have a few hundred PCs we connect to, and a team of 10ish guys who add/edit/remove computers/groups constantly.
I ended up adding my team as Contacts, and just make sure they share anything they add (manually) with all the contacts from our team with full control.
