extending UMMU / UCGO?

[AtomicDryad]

Hiya, is there a feasable way to use multiple airlocks with UMMU?
Currently I am having my selection routines call setactivedockfortransfer and defineairlockshape, however:
These functions do not appear to support pointers, and:
Someone outside in EVA can only enter the selected airlock.

I am getting around the latter issue with action areas, but:
Is there a way to define multiple actions / keys per area? If not, here's a feature request: adding a single new key in additional to enter would allow unlimited actions; enter activates while new-key selects an action.

Also is there a way to change the ummu hud or display an mfd?

And is there a means to create a custom dll-based mmu-vessel and have it support ummu's functionality?

Hi!
I would like to build a space station by DG-IV. Are there any add-ons(modules) with docking port which I could take a cargos for DG-IV.
