Very impressing, hits the sweet spot for projects that need a logo but don't have a big budget. A few comments:

* I skipped picking symbols and it generated a logo with a monogram. I wanted to get rid of this so I looked in the Symbol menu and was frustrated not to find it. I eventually found it in "Layout" but that's not the first place I thought to look.

* There's a lot greyed text used on controls, which is both hard to read and makes it look like the controls are disabled. e.g. horizontal scroll buttons, uppercase/lowercase toggle, text input boxes

* Logos on the preview page load slowly/inconsistently at times, leaving the sample images blank. Perhaps use loading indicators or don't show backgrounds until logo is ready.

* reloading the page loses your work (oops)
