Hi all,
I've released the next version of Simplify, v0.0.8, with support for SilverStripe v2.4 and several minor bug fixes.
Its now in a Google Code project, so can be downloaded or checked out from that:

If you find any bugs, want any features etc, feel free to create a ticket there under the Issues tag.
Cheers,
Dan
