Can anybody confirm that the removing of content from "movies" by a path-based rule as shown in the wiki/vid is even working at all on their Leia setup? Just tried on Win10 with a 18.1 nightly as well. Nothing is removed. Defining a "concerts" node by a path-based rule is no problem however. I don't get what the problem is, really.

 From my memory it does work but is skin dependent, you would need to change the skin to go to your filtered library.

For some reason there are 2 ways to launch the library items and I think the default Estuary skin does not use a node. @ronie may be able to explain or say i'm talking rubish  

 nope that is entirely correct. the details may be a bit too technical, but here's what it boils down to..

there are 2 directory structures in Kodi
- the internal 'old-style' db paths, e.g. videodb:// , musicdb://
- the 'new-style' customizable library node paths, e.g. library://video/ , library://music/

these new-style structures were meant to replace the old-style paths, but the implementation of library nodes in Kodi was never fully finished.
that's why many skins still (partly) use the old-style db paths. especially on their home menu.

as for the incomplete implementation, skins basically lack the ability to check if a library node still exists.
for instance, say i'm a user that only uses Kodi for music, so i decide the delete all of the video related library nodes.
ideally what should happen now is that all of the video related items should automatically be removed from the home menu as they don't exist anymore.
but that's the part still missing in Kodi and as a result you would end up with a somewhat 'broken' home menu.
