hungryDev89 I don't think it's technically possible on macOS for an app to present as a single item in the dock while having multiple entries in the ⌘Tab switcher (apps can hide their dock icon but I am fairly sure that also removes them from the ⌘Tab switcher so they become only accessible via clicking, Mission Control, etc - not via the keyboard) so the only options are either the current Orion implementation of each profile as a separate app therefore accessible from anywhere with ⌘Tab, or making profiles separate windows of the one unified Orion app instance therefore accessible with ⌘~ after first activating Orion.
Worth keeping in mind that while you might find the macOS ⌘Tab vs ⌘~ window navigation system (stubbornly?) flawed many people – myself included – vastly prefer it to e.g. the Windows approach of no distinction between apps and windows. Similarly I find multiple icons in the dock a benefit not a negative in addition to the functionality Orion's profiles being separate app instances provides including independent toolbar layouts, tab arrangements, app icons, preferences, etc, so whatever approach they choose will inevitably disappoint some people.
I guess it's up to the community to decide which approach they prefer to help the Orion team decide whether to make any changes.
