Shapes and components should be separate. Glyphs are (or can) be made of components. Components are made of shapes. I shouldn't need to go to a glyph to copy a shape--I should be able to select from a list of stored shapes to create a new component (just like I can select a component to make a new glyph. I don't see a library of shapes.

Add the ability to group together shapes

Once you have laid out all you shapes to form the glyph, it would be very useful to be able to merge selected shapes to form a single contiguous shape

Vertical and Horizontal mirroring works perfect, yet sometimes, It's just really annoying having to re-do certain parts purely because I can't rotate already existing ones by 90°- with this, I mean, for example a half ring.
Also, just rotating it and very carefully getting it as close to 90° doesn't work- the coordinates always seem to be very weirdly locked, probably because it's not really 90°, but 90.07 or something...

It would be faster to just drag guides, instead of setting the place values.

This currently cripples import of most SVG files that I have used.

A way to export and important glyphes as an SVG (or other file) File, maybe even a way to combine two fonts (like, having an old project font from 2007 combined with something of a newer days)

I'm trying to copy a letter of one font to send it to another, How do I do this (example. I like the D of one font, and I want it as the D of my font.)

id love to create a handwritten font but i cant seem to find any Program that supports it.

It's really nice to have all those guide and grid options, but they would be of much more use if glyphr actually snapped to those during editing (moving / scaling, etc.)

It would be nice if there was a button to move all characters up or down, to be able to fix fonts with the wrong baseline aka with characters appearing to high or too low.

Add Zoom thru SelectioAdd Scroll function to editing window view

You have some support for SVG fonts. How much of a stretch would it be to add full-blown SVG color fonts?

I think adding the ability to add glyphs from an image file would be a good thing to add, as it would speed up the creation process for those like myself who already have images made.

Please add export and import ufo font format

I needed a font with exaggerated spaces between letters and to achieve it I was able to change the left and right ranges, but then had to go to each glyph and disable auto-calculate on all of them. I only did it on the ones I actually needed. Doing it on all would have taken forever.
