Equations filter in Affinity Photo

[Andrew Buckle]

The equations filter is useful but the panel cannot be resized like the procedural texture as well as parameters (very limited)

1) Resize the equations panel so the panel can be longer / more width as if you enter something like rx+ry*2-oscsin(rx*rx+ry*ry)/1000+mod(rx,10) etc then it gets cut off and you have to scroll through it. 

2) Add more parameters - a, b, c are really not enough for many equations

3) Allow more access to similar functions that reside in the procedural textures filter

4) Add a presets feature, it is hopeless that you have to re-enter the equations each time

5) It should memorise the last equation used so you don't have to type it in again

Better still, add it to the current list of Live Filter Layers

Whenever I'm using the Equations Editor I keep Notepad or another text editor open.  I can then cut and paste the current version of an equation between the text editor and the filter. I can also copy the x and y values across as well. I can keep annotation in the asociated textfile which I save during the session.

It would be convenient to have an affinity text window as part of the program for such purposes, but my current workflow for equations is hardly inconvenient.

True, I do much the same but I just would love to see something like the procedural texture, a nice and handy presets feature as well as it remembering the last equation used.  As well as adding it to the live filter effects.
