That explains many things then. I understand not all of it was given. The XUL was still a learning experience (although I think I could do with some coffee for once), but I think it's best to release it as a stand alone when the time arrives.
As a lite version, some things are a given, but unless it's explicitly stated on what to change for a GM script (thinking about how many comments would have to be shown), I'd say hardcoded is best.
Without making this too harsh, the hardcoded defaults would be:
• General Linkify'ing
• Hard max of 25 images and 10 videos per page
• F/L/JMods posts will be colored accordingly in Forum View
• F/L/JMods quotes will have borders around them
• Highlighting will open in new tab
• 500ms delay on dropdown menus
• Post numbers #1-99999 throughout thread
• Forum Help links hardcoded (QFC might become quickly outdated)
• Save last forum post (How do you save without chrome.extension?)
I know you stated it before on a couple, but I'd skip:
• Custom Avatars (or provide them but make it clear you can't add in FF)
• Custom Posts (borders being obsolete with reskin)
• Blacklist/Whitelist (GM doesn't do well for this)
• Time Conversion (UTC master race; noting I'm in Oklahoma/Central US)
• God Mode and Mini avatars
• Custom BB Colour tags
You mentioned codes before, since using Linkify and before that from December 2012 (when I got here) to now, I've yet to see people use anything other than:
• Bump, Res, Lock, <3, and coffee. Five out of 148, the use is so small.
I know I faulted a few things, but it appears it was my own doing (page 700 was doing it to me for the spoilers, but probably lack of code is why).
There are advert codes from all sorts of entities. It's always a number and only up to three digits. It has always been /a=. Think of /a= as the referrer and adverts will be more targeted towards that /a=.
As always, it's been a pleasure.
