For some people, like my self, we may want to create entirely new letters with complex curves and symbols; therefore it would be nice to, say, draw the symbol on a piece of paper, scan it, edit it with a third-party "paint editor," then upload the resulting image into Glyphr. A three month font type, could be cut down to anywhere from fifteen minutes to a few hours. One imager, per letter/symbol/number.

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.)

Any other file types to consider?

Say, you've drawn character on a piece of paper and want to make something similar in editor. It would be much easier to do stuff if you could drag and drop photo of the character to the background of the main content area and then be guided by it through out the work. Of course, you should be able to adjust it according to grid.

Ability to select two shapes and perform a boolean operation on them, such as subtract and union.

Right now there is only Undo!

An automated way to export a package that contains all the font files needed for a proper web reading in all browser (.oet, .svg, .ttf, .woff), additionally include a css file with css code for implementation and a sample html file (similar to what you get when create a webfont on http://www.fontsquirrel.com/tools/webfont-generator)

Maybe with a drag and drop UI.

Some time you love one font, but it missing some glyph which required to work with an application, or multi language environment.

A Chrome Packaged App version with file autosave would be great.

Currently, the "Lock Aspect Ratio" box is unchecked by default. But usually when moving or resizing shapes, it's very important to keep the aspect ratio locked. It would be great to have this enabled by default, or be able to temporarily engage it with a shortcut (Like holding shift as with Illustrator/Photoshop/etc).

Needs a way to designate/design missing character glyph to show when character is not yet created in font. For now all font I create in Glyphr represent missing characters as tall rectangles that sometimes are taller than text lines.

Ability to make glyphs based on path stroke, not by using fill, as Single Line Font, export it in format similar to Rapahel cufon font, (it would be nice to have exported font gyphs having 0,0 coordinates at top, similar to svg image) I'm using adobe illustrator to design single line gyphs, then exporting them as svg, mapping to codePoint, and formatting them in json format for my use. It's a lot time consuming, iterative and irritative task. I would love to see your positive response on my idea.
Thank you )

It's painful to use when you need to delete multiple shapes one by one.

Improve the live preview experience: Tear it out to a new window, support paragraph-level previews, automatic word wrapping for sample text...

Currently handles can be locked vertically or horizontally. This would enable you to lock a handle to any arbitrary angle.

An automated process to take all the characters in a font and slant them at a specified angle.

Please allow copying / pasting vector shapes from AI.

Also, I was unable to open anything in Safari...
