Here's another suggestion on how this could be done in a slightly different way:

Every entity like stoXX, impXX, tskXX and so on has a name. The only entities that are not ensured to have (meaningful) names are files (filenames are not that meaningful in many cases). Therefore, a "named" linking could be achieved by making a reference to stoXX, impXX, tskXX and so on by making the linked text "stoXX: Name of story", "impXX: Impediment name", "tskXX: Task name", and, after adding a custom name/description field for file uploads, "fleXX: file name".

This would help to improve the readability of texts like "I need inputs on sto12, sto392, sto29 and sto291" where at present users have a hard time tracking down all these stories while being unable to rely on the "back" functionality, which does not work in many situations in kunagi.

For me, that "named entity linking", or however one would call it, would make the need for [[entityXX some other link text]] syntax obsolete. But, obviously, these two features are not mutually exclusive and could both be made available to users at the same time.

oh, i just noticed, that files already have a customizable label. So that doesn't even need to be added anymore. My bad, sorry :) Maybe however, this field should be available on every file upload form, so users don't have to navigate through the file repository after uploading their files, to only then set the proper label.

Actually, you can already view the name of the entity behind a short link. If you hold your mouse over a link named iss373, for example, a tooltip will show up saying "Linking files in Wiki".
