Having an elem_type of "signal-or-constant" that shows the same interface as when selecting the rhs of an arithmetic or constant combinator input would be really useful. This could then be made available on the LuaGuiElement by a combination of the existing property ...

It would be nice to be able to configure proxy containers to be logistic network members. That way you could easily expose any inventory to the logistics network.

It would be useful to have a function that, given a LuaSchedule (or LuaTrain/LuaSpacePlatform) and an array of WaitCondition, returns true or false based on the evaluation of those conditions.

While this could be implemented in lua by a mod itself, doing it this way is bug prone and will need to be ...

Thanks!

A small bump on this in case it was missed during summer

It would be useful to be able to read and modify the speed of asteroids at runtime. This could be used i.e. for making tractor beam turrets or deflector shields.

An alternative to having it be writable would be something similar to PushBackTriggerEffectItem that modifies speed instead of position ...
