make it possible to save patterns, like in FT2... BUT... don't just save the pattern data, actually allow exporting a pattern AS AN .IT FILE so it'll have the samples and stuff too. then when loading it just "append" its contents to the current loaded module. (should probably do something so as not to end up with 9 copies of all the samples when loading multiple patterns, dunno what.) this combined with the pattern-to-sample key might be a pretty good substitute for those who want a bazillion samples for all the drumloops and stuff; they can write the loop, render to a sample, save the pattern for future tweaks, then *delete* the pattern and associated samples (btw, should have a "clean up song" function like modplug that finds unused samples)... and if need be, can reload that pattern, fix stuff, re-render, and save it again. another use for this would be immediately apparent for anyone who's tried to mix two different .it files together for whatever reason. this way, just load the second file in this append mode, and blammo, two songs stitched together without any effort at all!
(delt says why do this if we have a clipboard. well, simple, try copying 30 patterns from one instance of schism to another with the clipboard, and loading all the relevant samples and remapping the instrument numbers in the patterns to the right places :))
