Going from blame-view to its commits is easy, say, "O" would open any. But ...

... where's the commit id in that new commit (diff) view? It does indicate tree id indeed, but not the commit hash itself.

I actually stumbled upon this when tried to revert a commit found with "blame". In blame's view it was impossible with crc/crn so I opened it and realised the described above issue.

BTW, I found out that tree id worked just the same way, but anyways it's better to have commit hash indicated there as well.

Commit hash is in the buffer name, and you can yank it with y<C-G>, or stick it on the command like with <C-R><C-G>. Next redesign of this buffer (no idea when this will happen) I will include it in the buffer itself too.
