What title says.
When you break a Quantum Entangloporter, it loses the Frequency it's set to.
I'd like to request that it keeps the Frequency it's set to, as you're very likely to use the same frequency (usually power) when putting it down, and if not, you have to open it anyways and nothing changes.
Also since side config is saved on the QE, different item/gas/fluid channels can very likely not be used without changing them anyways, so it would make sense to keep using the same Frequency.
Just my 2 cents of why it's a worthy QOL update ;)

Maybe this is already the case in 1.11.2 though (I'm still at 1.10.2)
