First of all Sean (Valhalla) thanks for that, we're really glad to have you on board as we are all devs and want to work closely with everyone. Of course we'll respond with a copy of Auganizer and you can test everything your end to conclude you're happy with how it works with your plugins
Secondly id just like to temper down some myths and/or fears here. Nothing we do is going to change compatibility with Audio Units in any shape or form past what your plugin is already compatible with (e.g. if it does/doesn't pass Logic's AU test). Its 100% the same plugin, but now given the name the user wants rather than the original manufacturers name. Remember Apple edits a lot more of a bundle when it injects its receipts into it for the Apple store.
*IF* Apple make any sweeping changes to the Audio Unit spec in the future, then those changes would apply to a developers plugins anyway and naturally if any naming conventions are changed specifically they'd also apply to the original versions of those plugins are we're only working in the AU standard. Ultimately with Logic there is actually no need to even work with any reference files or plists or anything else as part of the plugin, we could simply read the data, edit it in our own database and work directly with Logic - but this method reduces the amount of global Audio Unit hosts it works with, including Ableton, DP and Presonus One.
@Sean - there is the option to revert everything to stock with one button in Auganizer you simply lock the plugin, the one in the user folder is deleted and the original system file which hasn't been touched will be seen by Logic as originally instead (Apple programs will always load anything from the user directory over the system folder as standard). On top of that there is always the restore selected or restore all plugins to factory defaults (as well as previous session values if you want to roll back changes to one version ago) which again get you back to stock in a few clicks - when we launch the next update which will update system files this will be the easiest way to revert back to stock too. We'd still always recommend people have a back up of their system though, for obvious reasons, whilst Auganizer is totally safe, you never quite know if you're going to have a power failure whilst copying data, or a computer failure or all the other reasons to make sure you backup regularly.
To be honest any issues we've had in this thread with the exception of literally one or two plugins which do not like being run from the user directory (so putting them there was the problem, rather than changing the name they display) were all to do with Auganizer reading unusual strings or illegal characters from the plugins which didn't follow the same standards as all of the others - and the original issue with 32 Lives was quite simply because Auganizer didn't originally move the 32bit component with the 64bit one (so again nothing related to renaming) - we've not seen a single error/problem occur anywhere to do with renaming, and we shouldn't see as it conforms with legacy, current and future 64bit Audio Unit standards as laid down by Apple. We just have to make sure that the plugins are either happy to be moved or are being read/written to properly.
We really think people are going to love the new update. It addresses everything mentioned in all the threads, all the incompatibilities people brought up, most of the missing features and a whole lot more. We're really happy with it, its going to be ready really soon.
To finish up we're 100% confident the renaming conventions we have in place are 100% compliant with Audio Unit hosts and the AU standard just as all the original plugins are and very happy with the way we interface directly with all Logic versions and Garageband to ensure the user can do this quickly and easily.
