Glyph browser (#1636)

Dear Dusan,

I havily use iconic fonts, also known as glpyhs in typography. There are libraries of symbols that can be typed as text. I haven't found a way to insert glyphs directly in software ideas modeller.

If there is no glyph browser yet, I suggest to add one. (Examples: [3], [4]). Especially searching for character name and preview size adjestment are important to me.

As example: An important iconic font is font-awesome [1] but there are many of them [2].

Thanks for reviewing my suggestion and thanks for delivering such an outstanding product.

-Sebastian
