Design language

I've pretty much given up all hope of AgileBits deciding to go back on their decision to have their own custom cross-platform design language that doesn't fit in anywhere, rather than use the already existing and established design languages of the host operating system. I'm just tolerating the look and feel of the app now, rather than enjoying it - although the fact 1PW is fast helps a little.

any specifics you'd like to share

I'm sure all of these have been noticed before months ago, but they're still evident, so, here goes:

1. Non standard font. Instantly the app sticks out because it doesn't use the OS standard font (San Francisco on Mac)
2. No rubber-banding in scrolling lists. Another standard macOS feature.
3. The standard macOS highlights and accent colour set in the system Appearance preferences are not honoured.
4. Non standard menus, buttons and other UI elements.
5. Inconsistent right-click (contextual menus). Some are custom with icons and are truncated by the app window edges. Some are macOS style (even with the macOS font) but without icons and do extend beyond the window edges.

Over the months, I have seen improvements in some areas however:

1. Scrolling is no longer janky, and the redraw now keeps up with the fastest scrolling speed (even on my 2012 Mac mini).
2. The preferences window is now a proper floating window with the correct macOS style close button appearance and position, although the New Item window is still an old Electron style UI-blocking, mon-movable modal, with X to close top-right.
