It would nice to add Import/Export to the custom tools so it can be easily shared co-workers.
The best would be to select what tools are exported.
If I share my tools.xml with my co-workers', they have to overwrite their tools.xml and their custom tools will be lost.
We'll have to manually edit tools.xml cause I just want to export two of my custom tools without overwritting my co-workers'.
It's not a big deal to implement this kind of export/import (less than a day of work).
You already can share tools.xml.
