Extremely picky here, but seeing as a new IDM is coming out shortly, has the following spelling error been corrected?
After editing a file, the temporary screen should read:

"Your submission was successful! We are taking you there now.
Please wait while we transfer you..."

It's just I edit so many files and whenever I see "succesful" it jars me every time - I just keep forgetting to mention it on here!

If it wasn't reported to the bug tracker it's likely not fixed. I'd find any instances and report them to the bug tracker for 1.2.1 or whatever.
