I'm assuming that SP is done adding to/fixing I2 (and probably this forum as well), but if not, here are my suggestions:
- Fix Devourers/Titans dying twice as far as mission logic is concerned (looks like once when death animation starts, once when it ends): Can be worked around, but was a major thorn in my side until I figured out how to work around it
- Fix Never/After Any Triggered monitor reset options: The above issue wouldn't be an issue if the Devourers' and Titans' deaths were counted by the Never option
- Fix briefs fading in backwards: It appears, fades out, and appears again. It didn't do this before the 1.04 update...
- Add blocks of water that can be resized
- Add mortars, other militia skins, militia helicopters
- Add ability to select specific civilian (Silver Man, not Brown Man)
- Add Hive Lords (as a selectable option on the Ravagers since they're so similar)
- Add option to turn off Titan regeneration
- Add ability to sense object's distance from a moving object
- Add time of day options that are in I2, but currently not included in the editor (including lightning storm once player reaches that point); also, a way to change times of day mid-mission
- Add music that is in I2, but not currently in the editor (If the Beast music is abused, does it really matter? On that note, add the Beast and Behemoth)
- Add the background with the Beast in the distance to the time of day options once player reaches that point (if it is a background)
- Add logic to sense character's/object's health and trigger output if it falls beneath a certain level (for dialogue when boss is close to defeat, etc.)
- Add option to disable all powers except ionic charges
- Add platforms with grabbable edges that can be changed in size
- Add I1 enemies
- Add enable/disable option for Shadow Swarm in FoB
- Add the ability for logic to sense/change the amount of blood in the blood meter (if Cole runs out of blood, mission failure) and the rate of blood loss from standing or using Shadow Swarm
- Add option to make vampires not teleport, stick to walls
- Add catacombs editing (since there's no ground on most of the second island, it doesn't matter that you can't edit there without using some clever tricks; however, there is ground in the catacombs, and few tricks to edit there), as well as ways to restrict access to catacombs, surface world
- Add catacombs pieces to UGC (custom catacombs areas) as well as doors to link to said custom catacombs
