My game is starting to take a long time to preview, even after its graphics are cached - about 30 seconds at this point and there's a lot more code to come! Most of the time I'm only working on one or two event sheets, so construct spends a lot of time recompiling a whole bunch of code that hasn't been touched over and over again. My suggestion is for construct to cache event sheets that haven't been edited the same way it does for graphics.
Would this be possible for construct? If not, could it make it into C2?
