Would it be possible to add a -NoWait to Update-ADTGroupPolicy.
Having the option to wait or not wait to complete would be extremely handy when a GPO refresh can take quite a long time on some networks to complete or where we just need to trigger the refresh and move on.
Damn! This is a great idea but the wrong place to ask for NEW features
The best place is on the GitHub Site
lol... thanks @That-Annoying-Guy. I will post in github 
I see you raised the feature request in GitHub. :- 
I just commented on it, requesting a "NoForce" switch. I've used a custom function for years (- just an edited copy of PSADT's function with "/force" removed) called "Update-ADTGroupPolicyNoForce". It's faster not re-applying all GPO if you only want a check for a new settings/prefs to apply after an app installs. (I get there may be occasions you want the force/reapply all settings).
It would be good to have a single function with NoWait and NoForce. I suppose you could keep going and ask for "-Computer" and "-User" switches if you only want one or the other rather than both (again, to speed things up). Else we could just call gupdate with Start-ADTProcess and do our own thing, but I do like a PSADT function!
