Improved
- Resizable sidebar — drag it to the width you want.
- Selects and checkboxes are shared controls across Settings and every tool page, instead of the browser defaults that were showing through.
- Icons draw in the current text color, so they follow the button, sidebar row, or palette row they sit in.
Fixed
- Windows scrollbars — release builds rendered unstyled scrollbars while macOS looked fine. Setting the standard scrollbar properties makes Chromium drop every
::-webkit-scrollbarrule; they are gone, and both engines match again.
