I'm still chasing the idea of recapturing some of that.
My file manager is custom (and wildly promitive) because almost everyone has abandoned the idea of a spatial file manager (I don't want a "dogmatic" one that insists on one window per folder and reopening at the last position, but I do want Amiga-style ability to explicitly snapshot position and size).
My wm is custom because I want one floating Workbench-like desktop and a bunch of "screens" without floating windows.
My shell is custom because I wanted assigns and was willing to put up with a bunch of brokenness to get it.
I have a large design document I had Claude work on on a modern take of Arexx (I hate the language, but loved the ports; no Dbus is not the answer - the complexity runs directly counter to what make Arexx work, hence why we have a billion separate IPC command channels for apps today) that I intend to tackle soon.
I badly want to do something datatype like, but now we're firmly in territory that needs some community uptake to make sense.
I miss the excitement of the hardware too, but that is a lot more rose tinted, while a lot of the affordances AmigaOS provided are things I still actually want.
(Also, for anyone who wants to understand why we care about the Amiga without the couple of thousands of pages of Brian Bagnalls works on Commodore - which I hear ily recommend, but they're for people with a special interest - Jimmy Maher's "The Future Was Here"[1] is excellent)

Me too. I wrote a blog post about it: https://text.tchncs.de/r3nun0mxs9
