Really sad, indeed.
Anyway, below an example with the actual "nightly build" theme (except the last, I didn't draw it yet). I changed the color to dark blue, because it's better than black. But it's a pain because I have to:
- change my group names' tag in order to be the same as the ID name.
- change the group to a layer via the "Objects" dialog.
- After that I put each layer to the top level.
- And then I save_as "layer to separate svg file".
- Extract all files from the .tar created.
- resize the canvas for each file, clean unused defs, save.
Pretty long isn't it?
My point is: If I have to change the color for a reason, I have to change the palette for each file -> very long and boring.
A batch is possible?
I'd like to have a single .svg with all icons and when the program is starting, it checks individual files, then groups in icons.svg if an individual file doesn't exist. This way, it mill be much easier to share packs, and quickly change colors if wanted. Edit: No, in fact. But you get the idea.
By the way, is a theme gtk 3.0 creator available somewhere to make our own themes for Inkscape? That could be great (and useful).
