beta.46 Design, ⚐ Flags, div, fixed notify
Design/theme
Put a lot of work into tightening up pixels and made progress towards custom themes:

Here's a silly demo of me playing with theme generation:
Flags ⚐
An astute observer would notice that the Edit and Share tabs are now gone. They've been consolidated into a "flag menu".
When you press the right key from the main menu of script, the flag menu now opens up. This shows the selected script and gives you some options. It also exposes the keyboard shortcuts associated with those options that you can use to :

You can pass your own custom flags like so:
Notice that flag is a global while flags is an object you pass to arg. This is to help keep it consistent with terminal usage:

You could also run this and pass in all the args:
In the app, you could create a second script to pass flags to the first with. This is required if you need to pass multiple flags since the arg helper can only "submit" one per arg.
I'll put together some more demos soon. There are plenty of existing CLI tools out there using flags heavily, so lots of inspiration to pull from.
await div()

So the entire API should be available. Here's an example of using the "type inside a notification":
