The playlist method is much easier (I just tried it again) but if you really don’t want to go that way here is a convoluted path to what you want. Bear in mind that I don’t know what i’m doing. I just play around until I find something that works.
The first thing your going to need to do is change your skin to Estuary temporarily. Go into the movie section and you should see a double dot
.. at the top of the list. Click on the dots and in the menu it takes you to go to the slideout menu and select “Edit nodes”. Note that even though this brings up the Library Node Editor add-on it for some reason is different than opening the add-on directly, and why we needed to switch to Estuary.
The first thing we are going to do is hide the concerts from the movie node. Click on “Movies >” then “Titles” then click “add rule” and change the rule to path>does not contain>(path to your source). Now navigate back a couple times so your back to the first screen when you entered the node editor where it shows your main menu items.
We are now going to add a node for the concerts by clicking on “new node”, give it a name and click OK. Next you will click on the node>add content>movies. Click “add rule” and change the rule to path>contains>(path to your source). You can also add sorting here if you wish. You should now be done here so you can just keep backing out until your back on the home screen.
To make sure everything is working go back into the movie library, click on the double dots
.. and on that screen click on the double dots again. You should now see your new node so click on that and verify it is working. In that same screen you can also go to movies>titles>and your media from your concerts share should not be there. If everything is working as expected change your skin back to OSMC Skin.
Go to settings>interface>skin>configure skin>general>customize home menu> To change the movie shortcut to the node that hides the concerts with “Movies” selected on the left click on “change action” on the right and navigate to videos>movies>titles>
To add the new menu item click on “add” at the bottom of the screen. Click “enter title” and give it a name. Click “change action” and navigate to videos>(your node name). If you now navigate left you will see next to your new menu item up and down direction pointers. You can click on these to choose the order in which this new menu shows up.
If your wondering why you had to switch to Estuary to edit the nodes instead of having access in the OSMC Skin that would be a @Chillbo question
