Free Transform skew?

Is it possible to skew a glyph or part of a glyph manually rather than entering values in transformations?

Not yet.

If you’re planning to update that in the future, could you also do rotation of a glyph using trackpad gesture? That would be really handy. Thanks.

Rotating with finger gesture sounds cool but confusing. Two-finger dragging scrolls the view, pinching scales the view, but rotating actually changes the outline? In that case, it would make more sense to also assign moving and scaling to the finger gestures too (I do not want that though).

Those gestures are quite imprecise. What are you trying to do that this would help?
