Please allow multiple plugin instances with the same name. For example, if you insert 3 instances for FabFilter Pro-Q 3, Studio One renames the second and third instances as FabFilter Pro-Q 4 & 5! Add more instances and the plugins get auto-renamed with incremental numbers at the end.
Trying to rename a plugin to something that already exists gives the annoying "A device with this name already exists" error dialog. Again - multiple plugins in a session should be allowed to have the same name. Please get rid of the incremental auto-numbering of multiple instances of the same plugin!
This seems to happen only with certain third party plugins. Inserting multiple instances of Arouser, for example, does not auto rename them with incremental numbers. All Studio One plugins have this issue.
