Any 17.4 users out there?

IMHO - It's Cadence attempt to look like Altium. 

As mentioned below - new license file for Allegro required (In my case at least), I have only played with Capture so far.
I don't like the default dark theme - reason for this stated was to save power, yea I'll believe that one...
I love the ability to pull pages onto another window.

I have not played with pspice yet - no comment.

I how it handles the windows admin issues - we don't have admin privileges anymore on our boxes.

I like that the PCB is located project window, it should help to prevent errors in over writing files.

Only been playing1 day 

With glaucoma running in my family, dark everything is very much appreciated as I try to keep my eyes going until I can afford to retire. 

Since Downstream Blueprint and CAM350 also have dark mode, I'm inclined to think it comes free with the UI library Cadence chose.

I have to campaign for anything that makes Allegro easier for the occasional user EE...who won't shut up about how "awesome" P*DS is. 

If they're going to check out a board, move stuff around, check it back in with a million DRC issues with the note "can we release by 10AM tomorrow", for the love of God, we have got to stop using P*DS.

Getting some finicky EEs off Capture/PADS can be a major challenge. It's not that they like the packages so much, it's that they can make endless changes on the fly. Kind of like trying to keep flies off a pile of cr*p.
