+Quick notes to self:
+
+# How bubbletea works?
+Bubbletea is a
+Init ( once for sync/async opts both )
+-> Update ( model ) ( againc an be sync/async )
+-> View loop
+init creates initial model ( model is the global ui state and just a struct )
+update modifies model based on an immediate or deferred compute
+view is purely for rendering based on model
+
+notes:
+- model struct next -> global ui model
+- createModel is the initial sync model state population
+I anyways need to create the model struct even if blank
+- Init func is for bubbletea to call once at start so both are needed
+- all widths and heights are character count based
