First off, this tool is a lifesaver! Exactly what I’ve been looking for.
That said, I’ve noticed a few small areas that could use some fine-tuning:

-Adjusting the width and height for YouTube videos in dynamic QR codes
-Staying logged in when "Remember me" is selected
-Saving the default PNG size to avoid reselecting it every time
-Uploading files in the Meta Tags section currently doesn’t work
-The icon/image selection window in the Meta Tags section doesn't close after choosing
-The export window for QR codes remains open after exporting
...and a few other minor quirks

These are mostly just debugging issues. Overall, the system is excellent, and I truly hope it continues to grow and thrive for years to come.
