2/ different background for gaps between event titles on the same plane to create clearer, continuous separation. Events stay sticky, each plane scrolls independently only when necessary, and far left/right scroll shows roughly the same number of events across planes.
1/ Colorblind-friendly Calendar DayView, spacious so not reliant on color boundaries between events. Horizontal scroll is perceived as tradeoff, events near the edges easily missed. Mitigations:
Custom PDFViewController that works with native βFind, without tradeoff (everything else equal, particularly lazy rendering). Added another webworker to offload the math in text layer
`codemirror` wove in: undo/redo, pointer selection, text selection.
Alongside a `code_block` that supports marks, mention, img, KaTeX (or any type of inline)
