I've noticed that it doesn't show anything with applied energistics 2. Could you see about added compatibility or something? Like it doesn't show anything for AE2.

This would be perfect. Currently it just shows the AE2 event subscriber (which could be at like 200-300%) which really doesn't help, once you know that AE2 is causing the lag. If it could show controller locations of the setup that is causing the most lag (normally it's autocrafting), that would help everybody out.

Applied energistics 2 does sadly not tick in a conventional way (in the world), but rather uses the event subscriber mentioned before. I am guessing this is done in order to optimize AE2 networks.

This means that there is no context for LagGoggles to utilize, meaning that we don't have a location to work with.

If you really want this (I agree!) You should try and see if the authors/contributors can create their own simple profiler command for their own mod, as this is out of this projects scope. It doesn't have to be pretty, but I don't know all applied energistics inner mechanics enough to implement this myself.

Thank you for the advice. I'll try to talk to them about it.
