Have to agree, although branching off a new category might be a bit much. What if the mods were able to instead add a "marker" of sorts to the tiles...something like a "P" for the original format, and "I" for Intellijel's?
But yeah...the tile situation is becoming the mess that I figured it would when Intellijel started bringing out these not-exactly-1U tiles. Didn't like that then, still don't like it. At least Analogue Systems FINALLY had the sense and decency to start making their not-exactly-Eurorack modules with proper Eurorack power connectors and oval mounting holes to avoid the wacky .5 hp discrepancy problem. Seems like Intellijel might take a cue from that move and make it easier for users to incorporate their tiles into something other than cases spaced for that specific format variation.
