[ ] Icon to grab and drag assistant editor widget. For now I (tiar) used a `gridbrush` icon, but what I meant was that icon with 6 dots (three rows of two dots) in various software, especially web ones, that allow you to change the order of itemization.
{F10544324}
Intended icon: {F10544330}
[ ] For already existing actions "Show Assistant Previews" and "Show Painting Assistants"
Some suggestions: https://krita-artists.org/t/icons-for-show-assistant-previews-and-show-painting-assistants/40826
[ ] For already existing action "Toggle Snap to Assistants" - with a magnet icon
[ ] For deleting the assistant. For now it looks like "cancel" button, which is confusing. Suggestion: the existing trashcan icon. {F10572839} Can be something else, but I don't know what. "X" icon would be too confusing (as if it just "closed the dialog/editor widget"). Googling only shows one more icon, the one called `edit-clear` in Krita (X in five sides polygon, used to clear textboxes).
[ ] One icon for "Ellipse" and "Concentric Ellipse" assistants (it will be merged into one type of assistant, hence just one icon) - it will in Tool Options to select this type of assistant; like in Transform Tool you choose the type of transformation
[ ] One icon for "Ruler", "Parallel Ruler" and "Infinite Ruler" (the same as above)
[ ] Icon for "Perspective Ellipse" assistant (it's a new assistant in 5.1, it looks like an ellipse in a tetragon)
[ ] Icon for 2-point perspective assistant
[ ] Icon for Fish Eye assistant
[ ] Icon for Spline assistant
[ ] Icon for Vanishing Point assistant
