New Zoom Behavior | Better Link Display | FSEvents on macOS

This is again a smaller patch that improves many aspects of the app. As the last times, we have focused on improving very small but noticeable nuisances in Zettlr's behavior. One improvement we are very proud of is that after many years we have finally managed to get fsevents running. fsevents is a small library that enables us to watch your loaded directories for changes (so that if you add, remove, or modify a file externally, Zettlr can reflect that) without being too costly on your computer's processor. This change only affects macOS since the file-watching works already quick on Windows and Linux. You will be noticing this because changes to your files will be reflected (almost) immediately instead of with a delay of up to five seconds.

Changelog

This update changes the scroll effect on the document tab bar to be smooth
instead of snappy. To revert to the old behavior, you can use the following
Custom CSS:

body div#tab-container {
  scroll-behavior: auto;
}
