First of all, thank you!
This is the best tool out there, hands down. I've been using your little app for years.
I literally HATE every other file renaming utility out there. HATE!
I use less than 90% of the functionality usually, but when I need to make more complex changes, I just look around the app and usually i see exactly what I need and a path to accomplishing it. You have saved me from so many tedious time consuming tasks. Awesome App!
Also, I understand that you are providing a free service, allowing me non-commercial usage of your app, and I am very grateful to you. I make this respectful suggestion as your meek and humble user:
tl;dr PLEASE PLEASE PLEASE add back the ability to rename a single file using a mouse instead of F2.
It is SO annoying to have to use F2 to rename files. I understand that some users probably can't handle the power of this fast method of file renaming, and/or are linux users who hate being able to conveniently rename things with their mouse, so maybe you could make this into an optional function.
...but please bring it back. I had to download an older version just so that I could have this again.
Thank You.
