I think a block to manipulate variable watchers beyond simply hiding and showing them. This block could be a primitive, or part of a library.
Some functions I think it should include:
Change the X and Y position of a watcher,
Change the style (small, large, or slider) of a watcher,
And change the sliders min and max values.
Some more watcher features I would like (these aren’t as essential to the idea):
Create multiple watchers for the same variable,
Create watchers for custom values (any reporter you want),
Manipulate custom watchers,
Change the layer of a watcher (when a sprite uses GO TO front LAYER, it will cover up watchers. This is useful sometimes, but I would also like an option to have the watcher stay in front).
Yeah. I think anything you can do from the GUI should be doable in code (Eisenberg's Law) but Jens doesn't; he has to be convinced about each specific case. Don't hold your breath about this, but maybe someday.
