I miss a lot the ablility to have unique activity names from past activity syntax.
Sometime i define some paralell activity that uses/call same partition or activity. i would like to be able to have an arrow which i define myself from / to /style ...
we could have a keyword like @id <idname> before activity or fork or patition or note (in start of line)...
-> from to [options] to draw arbritrary arrow.defined
