Hm... OK. Dealiasing should be part of the grid. But for different equations the `aliasing_factor` could be different...

We'll leave this for future, not something to be done in #285.

Yes, ideally either the equation or the problem might be able to change the `aliased_fraction` property of the grid...

I'm pretty sure that RK4 should be faster. Both RK4 and ETDRK4 involve 4 calls of `calcN!`...

Should we do it? Do you have the capability @glwagner? Isn't there any good compelling alternative shortcut to that?

so we need to dispatch separately for *every* time stepper?

OK, dispatching each time stepper would be good enough for now :) I'll draft a PR...

Yes of course! Let's start with sane `ForwardEuler` :)

I like this; will try to do it. In `MultilayerQG` module in GeophysicalFlows.jl we have something towards that direction... https://github.com/FourierFlows/GeophysicalFlows.jl/blob/b15419e4fe093666c0b72cf1191328e631c5ed20/src/multilayerqg.jl#L258-L259 But what you suggest is better. Will `field` though always...

I might try to add GPU functionality to AlgebraicMultigrid.jl. @learning-chip, could you elaborate a bit more on what you are suggestion? If I understand correctly you are saying that we...
