There is some things to dislike about Layout and even SketchUp, but there is also a lot to love, otherwise we wouldn’t all be here.
Encountering a few issues with with SU 2023 myself:
This is probably good reason not to adopt any new software too quickly right out of the gate, give it a month or two, see what issues might arise and then go for it once it is apparent that things are going smoothly.
This particular bug is actually quite a show stopper for my Truss and Foundation plugins (since they still extensively use the UI.inputbox method). I’ve actually never seen this type of major bug before with any prior releases (since 2015), so I am a little surprised, but I get how things can slip through the cracks with software.
