Before I state what I'm looking for, I want to clarify that I'm not asking anyone to create any plugins for me. I'm simply wondering if any of these plugins already exist, and where I can find them if so.

Plugin to remove a specific amount of time from a split For example, if the first level of my run is 36 seconds but has a consistent 16 second load screen, I could set it so 16 seconds are removed from that split time. LiveSplit has a similar feature to this built in, which is the "Start timer at" option, but this doesn't always work. For example, with my above example, imagine the level is 36 seconds, but the total load time to be removed is around 6 minutes. Then the level would be split at -5:24 or something like that.

Plugin to force LiveSplit to a set framerate Because LiveSplit isn't running at the same framerate as the game I'm running, oftentimes my split time and the time I know I actually got won't match up. This is especially apparent when my split says it ends at xx.98 even though my game runs at 30 FPS, meaning the split is actually either a xx.967 or xy.000.
