The Rename command has been improved in Directory Opus 12, but it is not fully compatible with past versions.
One source of incompatibility was that the field in the Rename dialog that had input focus by default was the "Old name" field instead of the "New name" field. This problem could be adjusted with a script (a difficult task for pedestrians), but fortunately (many thanks for this solution!) since version 12.2.3.0 beta it can be set by means of the rename_default_focus option to Preferences / Miscellaneous / Advanced, to control which field in the Rename dialog gets input focus by default.
Another source of incompatibility is still present and has not yet been corrected. The Help file clearly states for Simple Rename that:
"If you don't enter a wildcard pattern, but instead just supply a literal new name, the function will rename each selected file in turn - the first file will be renamed, and the dialog will re-open showing the name for the second selected file, and so on."
This behaviour is described in the "Simple Wildcard Rename" section, where we also read that this mode "...is basically equivalent to the Standard Rename mode in the Advanced Rename dialog".
Well, neither Simple Wildcard Rename nor Advanced Rename in Standard Rename mode behave as described.
If I select two or more files, press the Rename button, change the name of the first file in the "New name" field, and press , the name of the first file is changed exactly as I want, but then the Rename dialog just closes and ignores all the other files. It does not re-open showing the name for the second selected file, and so on.
Of course this completely destroys 25 years of renaming experience with Directory Opus (I started my long and exciting use of Directory Opus since version 4 on Amiga computers).
I'm sorry if I've been so long and pedantic, but I already mentioned this problem in another thread (DO12 - Rename cursor 1st pos of new name box) and I presume that it was not properly realized there.
