If you're really going to force Eclipse on everyone, the least you can do is fix and FINISH the website first
This is meant to be a comprehensive, alphabetized list of all the features that are either tarnished by Eclipse or just flat-out removed completely. I plan on updating this as I discover more and more missing or broken things.
Feel free to contribute your findings below!
Removed Features: "Browse More Like This" search feature
Custom gallery folder icons (you can only use deviations)
Custom journal skins
"I Just Sold" profile widget
Image transparency in emote content previews
