I would like fixed insert slots (similar to Cubase) so that you can choose where to put each new insert plugin and that the same plugin slot GUI would open up when I change channels.
I would use this especially to have a channel strip / console emulation plugin (bx_console N) in a fixed slot when mixing. The console emulation would be in, say; slot 3 to allow for pre-console inserts (eg guitar amp emulation and VST instruments) and post-console inserts (eg effects and further specialist eq etc). This would give the effect of a virtual mixing desk.
