I really want to ween myself off of sluggish Adobe Illustrator and use zippy Inkscape. But with the projects that I am involved with, I require consistent and best performance on font control with the designers I work with. I would love to see the following items in a near future Inkscape, and if it happens, I can confidently endorse all the people I work with to start using it!

There are 2 specific font items that are holding me back:

1. Support for all fonts. Currently, I'm running Inkscape on a Mac through X11, and all my fonts don't show up.

2. Support for different measurements. For example, I can only control line-height percentages, instead of specific pixels or ems.

I don't have much programming experience, but I'd be happy to do product testing! Let me know how I can help!

For item 1, have you raised a bug? Also, when you say "all" your fonts don't show up, do you mean that none of them do, or just some? If the latter, put in your bug report the names/sources of fonts that are failing - they could be a different type or badly constructed (as you probably know some freeware fonts aren't put together very well, and some graphics packages behave poorly with them. I know this is true of Scribus, it may be true of Inkscape too).

For item 2, I believe feature requests can also be raised as bugs here: https://bugs.launchpad.net/inkscape/+filebug
