Organizing Favourites in Finder with Symlinks and colons On my machine I have repeating patterns of directories.

E.g,:

notes/2019-01
records/expenses/2019-01
records/taxes/2019-01
customer/project/notes/2019-01


Links in the Favourites bar show up as:

2019-01
2019-01
2019-01
2019-01


To get around this, I'm creating symlinks to point to the folders I'm regularly using.

MacOS lets me rename the symlink in the gui, and it seems to accept unusual characters, even '/'.

so I can create symlinks like:

notes/01
exp/01
tax/01
proj/notes/01


But... on the command prompt, the '/' is a ':', which is a surprise.  I've not seen this done in other Unixes.. maybe I've never noticed.

Is there a pitfall to this? am I tempting fate with slashes and colons here?
The filesystem internal separator is : on HFS which is why other Unix don’t existing that generally. There’s no harm I can see to what you propose as its portable across Unix in my experience and harmless on macOS
