The geeky part of me likes this idea, but I think I would regret adding it. It’s an interesting and clever solution, but it’s not the way that a normal Mac user expects to use an app. I think few people would understand it right away, it would just make Bike feel more complex.
Longer term I do plan to add a standard library feature to Bike. At my current rate this will take a while, but I expect I’ll get there someday.
In the meantime I think the core of this hub idea can already be implemented with scripts/actions and keyboard shortcuts. I guess that’s what you are already working on with your shortcut actions post? I’m going to eat some lunch, and then will finish up and post next preview of Bike that will fix the focus issue.
Lets see how far we can push this hub idea with automation!
