I'd really like some sort of bulk upload feature on a per-section basis due to how time-consuming doing it manually can be. Submission names would be based on the filenames and thumbnail filenames would probably have to be the same to ensure they match up correctly.

I get that it's somewhat impractical to submit a ton of stuff at once right now but we specifically did not include a bulk upload feature as it could too easily be abused.

Maybe use htmlspecialchars() to replace dangerous characters with HTML entities on the main four websites instead of the current system that can result in the removal of text.

Where are you referring to specifically? That function is indeed used in certain scripts but not all of them.
