Hello!
I have made some modifications over the theme from Guillermo Espertino.
Guillermo and me have been talking and we think that this new modifications could be a nicesolution to renew the default icon theme but no tango-ished too much it.
I have redesigned some tools to use the original ones but adding a consistent look and ensure the correct grid align and visualization over dark and clear background.
I have retouch the border of some tools like some of you have suggest.
I retouched the Text Tool to allow a little more constrast with dark background.
And some others minimal changes. ;)
I hope you find this way as the correct one. ;)

Pdta:
Only one thing more: please be polite. This work is not simple and is a work that requieres time and effort. So, please, avoid to convert this mail thread in a war between pro-Tango and anti-Tango or a list of unviable particular personal wishes. We must think about the usability, technical issues, and problems with some icons wich could not be correct. But alwais send constructive ideas, please.
We could, together, improve Inkscape. Thats the big rock. ;)
