Throughout Toy Box building, has anyone else wished that they could use a Terrain theme on a Basic Building Block? Or a Basic Block theme on a Terrain piece? The two lists already have a fair number of shapes in common. Perhaps they could be merged .
This could free up an entire Category of toys (after moving Blip Blocks, etc. to Instant Fun for example). But the combined list of themes would be unmanageable. Some might argue that the separate lists are already unmanageable, and with 3.0, 4.0, etc. the usability of that fundamental Artist's Palette icon comes into question.
There's already some filtering options within Spark mode to limit lists of toys on the edit ribbon. I haven't experimented yet to see if you can limit the themes. And are these filters associated with the user/builder profile, or with that specific Toy Box? Do you need to reset them every time you start a new box or re-load an existing one?
What if there was an Artist's Palette Creativi-toy that you could place down in a Toy Box that could store the themes used in that particular box? In its Properties you'd choose what toy Category it handled. You could choose say half-a-dozen slots of your "Toy Box Palette" for any given category that would make for quick selection during editing. You could plop down one of these Palette toys for each category and make the theming within each Toy Box considerably easier. Conceptually & visually, it would be more straightforward to have a particular Toy Box's subset of themes centralized within one or more Creativi-Toys.
Plus, what if there was a level of indirection within that Artist's Palette toy? What if toys were designated "theme 1", "theme 2", "theme 3", etc. You could program those particular themes into that Artist's Palette toy. The visual interface would keep it simple, and yet it would then be possible to make ALL themed pieces in the Toy Box programmatically re-theme-able in-game. . Push an Action Button for example, and have a third of the Infinity trees, half of the Terrain, and all of the Platformer toys change as part of a character's magical adventure. If the Palette was subsequently deleted or adjusted such that "theme #" was lost, the toys could "revert" to their default theme.
P.S. Still waiting for that curved Hedge corner in Plants to move over to Terrain so that it can be themed differently. That toy looks really cool; it gives walled areas a nice rounded feel .
