Right-click options for multi-selected Local variables to change all to read or all to write. Just like the 'Change To Read' and 'Change To Write' options that are already on a single local, but for multi-select. If they're all set to the same direction, then that direction is grayed out in the menu. If there is a mix, both options are available.
This plug-in was originally requested here.

This is great stuff and I only gave it a 4 star rating because of the rating rules: I wished it worked for more than local variables (which was my original request): global variable are an obvious extension (though rarely needed, hopefully) but Property Nodes are another more useful variant.
