Since this seems to be the custom model update:

• Custom weapon models
• Custom vehicle models
• Custom pickup models
• Custom textdraw sprites
• Custom textdraw fonts (I would really like to use the killfeed icons/gtaweapon3.tff font)
• Custom mapicons (think of GTA3 and VC mapicons)
• Custom sounds (AudioStreams are nice, but they can have a bit of a delay)
• Custom map

Other suggestions:

• vehicle variants (for example a NRG sometimes has 1 pipe, sometimes 2, ... would be nice if we could optionally force one to be used)
• player pickups
• set objectives on players (like exists for vehicles now)
• custom train track nodes
• chatbox tabs (to prevent the chat from getting unreadable)

And as suggested before, custom cullzones and the ability to remove the current ones.
In the SA installation folder is already a file "GTA San Andreas/SAMP/SAMP.ipl" that adds custom cullzones. Doing this programmatically and serverside would be awesome.
