As someone thinking about upgrading to a stable Cubase 5 to 7, it's so disappointing to find that my most wanted feature is STILL not available.
As a developer myself I can't believe that some kind of plugin tagging system to allow users to organise their plugins as their workflow dictates is either
1. Too much to ask when people are spending large amounts of hard-earned money of the platform and the plugins
2. Particularly complicated from a development point of view; it's small fry compared to things like VariAudio etc.
3. Ridiculously overdue - having to either hex edit my plug or keep remembering that I won't find my Duende plugs in my dynamics path...from the creators of the VST standard as well...
FWIW, I do think that the design of VST3 by having plugins fixed install would have been a good thing if there was a universal tagging solution (and ideally this solution would be agnostic to whether the plugin was VST3 or VST2), as these aspects should be separate; how I access my plugins should NOT be a function of where it physically exists!
While being able to search is an improvement, it's still not good enough, and certainly not enough to get my to move to 7 with all of the changes to the mixer to factor in...
