Wish: Bongo render - Initial frame suffix not clear

The following setting produce frame images named 0578 to 0868.
instead of frames 0289 to 0579 as I was expecting.
I supposed that I have been duped by the Initial frame suffix. I should have let it to 0 (?).

Could you add, near initial frame suffix, the name of the first file and the name of the last file to avoid errors.

Sounds like a good idea - but yes, a combination of a specific range and a non-standard initial frame suffix is probably a bit confusing.
