sticky arrows/arrows in Marvin 5.10

In Marvin 5.4, it was possible to stick the starting point of arrow 1 to the midpoint of arrow 2, so that if I moved arrow 2, the start of arrow 1 would follow.  In Marvin 5.10, this is no longer possible.  I would like you to reinstate the behavior.

Hi Bob,

This bug has been fixed so in the 6.1 release it will be working again.
"Lost feature of sticking the end of an arrow to the midpoint of an existing arrow was reinstated."
Thanks again.

Best regards,
viktorw

Thanks.  6.0 was just released.  Is there an estimate of when 6.1 will be released?

6.1 estimation: end of August.
