 - retained mode
- specifically designed around wgpu
+- specifically designed around wgpu so there's no translation
 - postfix functions for most things to prevent unreadable indentation (going very well)
+- events can be done directly where you draw the widgets
 - almost no macros in user code & actual LSP typechecking (variadic generics if you can hear me please save us)
 - relative anchor + absolute offset coord system (+ "rest" / leftover during widget layout)
 - single threaded ui & pass context around to make non async usage straightforward (pretty unsure about this)
