I’m so happy that they implemented this (the devs keep crushing it!). Obsidian has become central to my workflow and I sure hope this tool lives long and prospers!
(I am even more delighted that they decided to go with [[Name|Alias]] – I spent a whole day lobbying the Discord supporter channel for this This ensures complete portability but even more important, that means you can change file names from inside Obsidian and aliases, nothing will ever break.)
I’m pretty sure DevonThink already supports this.
They support aliases in their non standard way, and not the pipe syntax as far as I know.
