Mathias,
When I do not use the (On Target) folder creation command, the folder is crated in the current panel BUT the filename that I selected is not inserted into the dialog box.
I have found a work abound that might be useful to others:
1. I created a user user command, using these parameters: Internal Commands > Explorer Panel > Files/Folders name.
2. I went to: Explorer Panel Settings > Mouse configurations > Custom mouse command #1; and selected the Files/Folders name User Command.
3. I went to: Explorer Panel Settings > Mouse configurations > Left mouse button > Click; and selected Custom mouse command #1.
4. I created a user command, using these parameters: Internal Commands > Explorer Panel > Create folder (From clipboard text). This command creates a new folder in the current panel.
Now I can single left click on a file, and the hit the Create folder (From clipboard text) button, and the dialog box with the current filename is copied from the clipboard and all I have to do is remove the file name's extension, and the folder is created in the current panel.
Maybe in the future you could tweak the program to not copy the file extension into the create folder dialog box
I have attached screen shots.
Thanks.
