Allow Wider Sidebar for macOS version

[CarlMangno]

Describe your feature request Please allow the Sidebar in FSNotes macOS version to be resized to a greater width so as to show longer folder names. This can especially become a problem with indented nested folders.

Finder allows the Sidebar to be resized to a much greater widths so as to easily see longer folder names.

Notes:

• In FSNotes macOS version, currently the Sidebar can be resized to show up to approximately 30 characters, and fewer than 30 for nested folders that are shown with disclosure triangles.

Additional context MacOS Version 6.8.0 (626).
