Good suggestions yes. Strong ideas. Ultimately the desktop has been content to let the apps take over more and more, while not extending itself. Actually making the OS something that actual activity happens on feels absolutely essential. Making a Raycast/Vicinae (the pretty great open source port) integral feels like it would go a long way towards this end, of offering a consistent way to expose & access the toolbox.

I'd love to see an agentic OS where the OS and apps can both talk in terms of MCP things like resources, tools, skills. Yes these are primarily geared towards agents, but they are also acceptable machine-to-machine interfaces to script against too (so long as the type signature remains compatible).

Android's Intents feel related, similar-ish. It's a pity no one bit on PK's WebIntents. That could have been an interesting way to create abstractions for intents, for activities, for stuff happening on the computer. Notably the xopc actually had activities and a journal that let apps contribute meaningful intent to the OS as a whole. But mostly it just ended up as a history viewer there. Android mostly uses intents as a launcher. But this idea of having the activities of the system as available abstractions could go much further.
