a long time ago (0.15? thus i don't remember any details) there was a mod that for some types of tiles was able to convert them back to their base tile by having them on the cursor and pressing "J".
since there are several mods now which have similar problems (eg all the markers in LogiCarts, all the different types of colored and striped concrete in several mods, etc), i would like to have such a general function, and that of course should be a separate mod so that it can be mixed and combined with any set of this and/or other mods.
but i have no idea how this can be made to work easily with many different tiles and mods (maybe some API in that new mod where all interested mods can somehow register their tiles and list your new mod as an optional dependency?). else (if it works ONLY with the asphalt of this mod) it probably would be best to include it in this mod.
ps: i might have found a very tiny bug in this mod. when i had installed its optional dependencies, the "Wood-Gasification" was still shown in orange and not white, and clicking the arrow in front of it couldn't find it. i believe that the reason is simple: that mod is named "Wood_Gasification" :-) :-(
not tested, but i think that also for "Bio-Industries", the correct name would be "Bio_Industries" ...
