Using Pro 3.5.1
EDIT for clarity
Currently, when you select a file in Catalog and press F2 to rename it, the full file name text is selected, along with the extension.
Please change the behaviour to match modern file management tools and only select the file name and not the extension.
Based on the file type, Pro may or may not allow you to change the extension. (e.g. shp, jpg, etc not allow; pdf allow).
Having to change the selection EVERY TIME you want to rename something and you're not sure if the file type includes fixed or changeable extensions, is inefficient
Original with silly joke:
Currently, when you select a shp file in Catalog and press F2 to rename it, the full file name text is selected, along with the .shp extension.
Please change the behaviour to match modern file management tools and only select the file name and not the extension.
I am not currently aware of any benefit to rename a shp file to .tab 👽 and having to change the selection EVERY TIME you want to rename something is inefficient.
