Inkscape is a blast! I do some (simple) icons and the features are amazing. As for the new version 1.4:

• The new Filter Gallery is really nice, but usually I don't use filters anyway.
• The Swatches Dialog makes my life easier too, but for whatever reason I don't get the color names. It only shows the color codes s #669900. Anyone know where to set this?
• Unified Font Browser is also now up to standards and makes it a breeze to play around with fonts. No longer do I need to explicitly apply, just left click from the list will automatically update the canvas text.
• Shape Builder is really a cool functionality and I always love to use it. It saves so much time when needed, or can lead to unexpected cool effects. Now it works with raster images, to cut parts out. But they can't be edited or Trace Bitmap unfortunately. The article talks about Release Clip and unlink clone, but I don't know how to unlink clone. Hopefully this can be worked on to make it more seemless and easy. Shape Builder in general is OP (over powered).
• Dash Icon set is nice, I'm trying it out currently. Each icon is clear.
