Feature request: Predicted or Intermediate state of uIElements

Well as usual it all depends... but you are basically correct. If extending the existing node then yes the basic behaviour should not break any existing users - but also it should not add too much complexity to the config options, and indeed most are fairly busy already.

Extra nodes are always welcome - but ideally they should be new types of widgets. So yes a tricky balance - but we are always happy to discuss concrete proposals before you start writing code.
