Additional Grease Pencil Effects

Coming over from Adobe Flash/Animate, I want to propose a few new effects/additional options for effects that were in Animate that will make switching between the two programs easier.

1. A new Outline effect that can be of any one color and thickness (This is actually possible with Geometry Nodes but doesn't account for fills because you'd have to make each of them cyclic manually, so I feel an effect is the better choice)
2. A Flash-style glow (the current glow is amazing but doesn't work for a simple blurred colored outline. This can just be an option for the existing glow effect to choose a color, intensity and blur amount. This can also be an option for the above outline effect where you can replicate this simply by blurring the outline.) This can be worked around by linked duplicating the GP object with the outline geometry nodes I made and adding a blur effect to it, but I think it's better to just have one effect for this.
3. Inner shadow (Can be an option under regular shadow but it instead masks the shadow inside the object, with all the regular options like blur amount, position, rotation, etc..) This can be sort of worked around through two rim modifiers but it is unwieldy in my opinion.
