[RebeccaDeField]

In this pull request, I have recreated the Dual Filter plugin redesign proposed by @simonvanderveldt in #3093 as a part of our efforts here.

Sorry I was busy so I didn't have time to comment.

The box size is off by 2 pixels, and the third knob's position is off by a pixel. I'll post a fixed mockup asap.

Actually, sorry, the knob spacing is not the same on the 2 boxes, it's either 1 or 2 pixels off. It should all be on the same value and the padding of the box should be the same on both sides.

Here, I made the boxes thinner by 1px, aligned the knobs in them. I also changed the boxes' position so the spacing between the edges and the mix knob is the same. I also reduced the size of the dropdown by 1px.

These are unfortunately not code changes, just a quick mockup

[Umcaruje]

It looks even better to me if you deliberately move the knobs 1px off horizontal center, cause of the LED

[Umcaruje]

Also do we want a line connecting the boxes like in the stereo matrix plugin? So it's clear the mix is between the two filters?

[RebeccaDeField]

@Umcaruje Wonderful feedback, thanks! A mockup works just fine for me. I'll play with the spacing and try your idea to connect the boxes.

I'm merging this in 12 hours if there are no objections.
