Sortable Tolerance

Sortable Tolerance


HI all -
I'm working on a web app that has a three column layout, each column
containing a number of modules that are sortable. Each module has a
handle that is a nested h2 tag.
Everything is working, now I'm concerned with tweaking it to improve
usability.
At the moment, when I drag a module, the portion of the module that
needs to be atop the sortable container is kind of awkward: it's like,
the lower third of the module.
Now from the source I don't believe that the 'tolerance' option can be
used on sortable, only droppable. I'm curious as to whether or not
there are plans to implement something like 'tolerance' for sortable?
Or if anyone else has hacked together a solution that would work
instead of tolerance? Or is there another way to sort of tell sortable
what portion of an element it should be interested in receiving with
the existing api that I'm overlooking?
Thanks for any advice you have to offer.
