Dan's userscript takes longer to load
It loads really quickly. The only thing that significantly lowers performance is that if you enable my userscript and Muli's userscript is that after around 2-3 seconds of loading certain pages (such as the all forum posts page) something causes the layout to look bad (extra columns to the left would be added), so I added a way that fixes the visual error (by removing the extra columns). Also, the bigger the script is, the longer it'll take for it to load, hence how my other script* loads faster. I know of ways to simplify the code further but that evolves using jQuery and I'm not all that familiar with jQuery. In comparison, Muli's userscript has a file size of 686KB while mine is only 121KB.
makes the forum uglier
In my opinion, it looks better if the background is a gradient rather than a solid colour. If you press the F12 function key and search for 'table.region tr' you could disable the CSS rule that says something similar to or includes 'background: linear-gradient'.
adds options to unhide things
How is this a disadvantage? If you've hidden something, wouldn't you want to see it again? I could make it 'optionable' to not show hidden things.
doesn't do anything to downvoted threads
What do you want to happen to downvoted threads? I added a feature that lets users hide and show downvoted threads as often as they like, instead of only being able to show hidden threads and not hide them again.
didn't know when to stop and kept on adding stuff
If you read the first post of my thread then you would have noticed that I'm currently working on bug fixes. I'll keep on adding to it until I can't think of anything else to fix or add to.
* = Wally didn't create any of the code himself and technically, I own it. Don't debate who owns it here; PM me instead.
Edit:
Unlike the other script, my script has a user interface (UI) and it's really easy to use. With the other script, you actually have to go into the code and add to the Block List there. Using the UI, it's easy for you to do this process; it's only one click of a button at minimum to add a player to your Block List.
