Echoing similar sentiments to other posters on the forum…
Pretty please change the help in designer back to the old-style help browser which we got in R8 and previous, or at least give us the option to use it.
At the moment if I want to use help I swap back to the client and manually open the 8.5.1 designer help then do my searching because the side-pane help at the moment is un-intuitive and thus frustrating.
Like many others the thing I used most in previous help was to hit F1 > then choose “Index” and start typing to find what I wanted or swap to the search pane if I wasn’t sure and needed to hunt it down.
Regards,
Craig.
