Chris Wraight's final moan raises a very interesting topic. On occasions I have tried personalizing the toolsprites, and just using !Paint it is a tedious and difficult exercise. No doubt with ArtWorks it is a lot easier, but I suspect that ArtWorks only works on a sprite by sprite basis. No, what is needed are "scriptable" tools for creating sets of icons; something that lets you work at a much higher level of abstraction and under automatic control.
I look forward to the release of the RO5 sources of !Paint and the other applications, because I want to make them all scriptable. I recently sent an email to ROOL on this topic. "Configurability" means user control of constants, strings and numbers, in an application. "Scriptability" means user control of key functions, such as event handlers, as well. My roadmap is to construct a shared Lua library with which !Paint, !Draw, !Edit et al could be linked, so that they could be controlled not just by mouse and keyboard input but by scripts as well. Any kind of application for creating sets of icons sharing a common theme would have to go along some such route. Anyway, I have to be careful to catch my hare before I skin it.
