Maybe it's just me and I haven't yet discovered the right way to use this. I would like to be able to select the format of module I want to see, 3u, 1u or both. However when the 1u box is unchecked (by default), both 3u and 1u modules are listed.
So something like this

[x] 1u / tiles
[x] 3u / modules

with both controls individually selectable, would give me a chance to view 1u or 3u or both.
Lest I forget, great work so far on the 1u integration.
