i think there should be odds and outs calulater for the HUD or somthing like that for ppl who multi-table a lot would make it so much easier

PT4 doesn't have any information about the hand in progress so this kind of thing isn't possible.

although this may be the case, could such functionality not be developed, as it is included by at least one of your competitors?

I do not expect this to be added to PT4, although it may be reconsidered in a future version.
