Thanks for the suggestions puppy!
Reserved slots are in the process of being implimented, expect to see them soon
If you can think of a good shortcut for measure, let me know. /help short will give all the current shortcuts.
More doors are being implimented
/ban @ [name] will probably not undo all actions for sop+, but it could do a very large amount (24 hours maybe). Example being when you ban a builder+, it will take forever undoing a weeks of their actions, and will lag the server respectively.
Monthly themed map sounds good, will need a community vote though.
The glitch with /color and /tcolor is when custom colours are used in /title. The last colour used in /title (IE: rainbow title) will override the colour of their name. This only effects the colour of their name when typing, not above their heads, and usually typing /color [name] del can fix it. A workaround is to set the user a title, then change the colour of the title, or remember to set the colour to their rank colour after setting a multi-colour title. The only downside to the latter is that when the promotion comes along, their title will need resetting.
HawkServ already has the feature to "load on /goto", it's just not active. The only negative is that this could double the time it takes for players to /goto, especially on large, filled maps. With the current issue that Minecraft 0.30 has where it shows a black screen instead of a loading bar when changing worlds, this could 'trick' users into thinking the server, or a map, crashes their client.
I'll take a look into the more colours feature, however i think that they're all hard coded into the minecraft client. If colours can be replaced, you'll need to think of ones that aren't used , or more hex values. (Incase you haven't noticed, all the colour values are 16bit HEX, from 0 to f)
But please do, come up with more
