I agree, it's an awesome concept in principle (and Girba is graciously welcoming people in discord). Working with an agent in GT, the agent will just look at the data and figure out how to express it in the graphical framework.

But in practicality, at least at this point, bb wins out by sheer expansiveness of ecosystem. I was working on a mishmash of an editor interface that combined obsidian with heptabase, directly in GT. It kind of worked. And the amazing thing is, everything has just a single representation: window positions displayed as text automatically have 2 way bindings across widgets, because they are the same data. But even with agents doing everything, 2 things creep up.

First is in JS/TS, all these binding problems are solved 1000x already. You can fake shared memory with callbacks and the agent won't lose track. In GT you move the cursor around, and have to decide at what point do you convert a widget representation to source representation, and when to restore the widget: is it a delay? is it after changing lines? is it after you move off the text? before or after the whitespace? There's a package for that somewhere in npm that answered all these questions, and it has tables, and it's performant. It doesn't do the 2% stuff that GT does using its magical shared memory representation (which also makes TS->smalltalk porting not straightforward), but you can still tape over it with sheer optimized code.

The second thing is that GT got really slow with all the data structure re-interpreting and rerendering. As "dirty" as bb is in reloading dynamic code, the runtimes are so optimized, I wanted the markdown nodes to be GPU-accelerated in bb, and it turns out they already were.

Do you have any recommendations for starting points with the bb ecosystem? As in, good existing components or practices?

I've been using it on and off for a while, but never got around to doing any major customisation mainly because I hate reinventing wheels (and also I was busy with other things). But I now am looking for something like a cross between Warp and Zed's Delta (which is a very nice design), and bb might be able to give it to me.

EDIT: OK, the plugin marketplace is much more browsable than the last time I looked. It'd be lovely to have a gallery where people can show off their own configs. Maybe I should make one...
