any plans for parallel bandpass filters - very useful in sound design

I guess this is about apQualizr2.
It already can do parallel bandpass filters.
There's the harmonic band-pass filter type that allows for many bands of parallel bandpasses.
In the latest versions, it's also possible to create a side-chain structure to do parallel bandpass filtering. A gain filter can be used to create a side-chain that can be filtered in parallel and merge to the aux input of the output module.
There is actually a preset included to demonstrate this: "Parallel/Moving Parallel Bandpasses"

In addition to the harmonic band-pass filter type, since v2.7.0 or apQualizr2, there is an aux input on the output module that allows for parallel filtering in general.
