### Changed
- The maximum number of delaylines in the native synth was increased to 128,
with slight increase in memory usage ([#155][i155])
- The numeric updown widget has a new appearance.
- The draggable UI splitters snap more controllably to the window edges.
- New & better presets, organized by their type to subfolders (thanks Reaby!)
