Hello,

I’m writing course slides in org-mode (exported currently to beamer, but
I want to also have html export in the long run), and I have trouble
linking blocks (for theorems or definitions), as the CUSTOM_ID property
is ignored by ox-beamer on blocks.

I see this issue has already been raised on the list
(https://list.orgmode.org/87lflg9ts2.fsf@nicolasgoaziou.fr/T/), and
looking at the code it seems that it still needs to be modified.
Unfortunately the code for org-beamer--format-block is quite complex and
I do not see how to change it to add a label. Could someone on the list
please give me a hand?

Best,

Alan
