Hi KK
I read through both of those before posting, and have read through them again, and I'm not sure that they do. I have already grouped all of my templates into various folders, and now it is just this one folder which contains 12 pages that is particularly messy still. The way I see it, I have 2 options:
Option One - break these 12 templates out of one "Tags" parent folder into 3 different sub-folders, each subfolder containing 4 templates. For example, in my specific user case this would be:
Current structure:
---Tags---
UK Patent Tags
EP Patent Tags
Foreign Patent Tags
International Patent Tags
UK Trade Mark Tags
EU Trade Mark Tags
Foreign Trade Mark Tags
International Trade Mark Tags
UK Design Tags
EU Design Tags
Foreign Design Tags
International Design Tags
New Structure:
---Patent Tags---
UK Patent Tags
EP Patent Tags
Foreign Patent Tags
International Patent Tags
---Trade Mark Tags---
UK Trade Mark Tags
EU Trade Mark Tags
Foreign Trade Mark Tags
International Trade Mark Tags
---Design Tags---
UK Design Tags
EU Design Tags
Foreign Design Tags
International Design Tags
I don't particularly like this approach, since I currently have 7 folders of templates already, and this approach would add two more. It also, IMO, would be less user-friendly.
Option Two - break up the list of items within the folder, using horizontal lines. For example, in my specific user case this would be:
---Tags---
UK Patent Tags
EP Patent Tags
Foreign Patent Tags
International Patent Tags
--------------------------------
UK Trade Mark Tags
EU Trade Mark Tags
Foreign Trade Mark Tags
International Trade Mark Tags

This is what trendoman has provided a solution for here, and I am more than happy to use these 'dummy templates' if that is the way to achieve this layout (i.e. grouping / breaking-up a list of templates once they are within a folder). I just wanted to check that there wasn't a better way of doing this, since the new versions that have come out since trendoman's solution was posted in 2016.
I am assuming that the "------------------" lines within the folder will be clickable, as if they were templates, and that they will display a template with no editable regions (I appreciate that trendoman has provided a method for customising how that appears to the admin). Also, this method requires additional php pages on the server. These are just two reasons that I was hoping there might since have been an alternative solution to achieving the layout - but, as I say, I am happy to use the present solution of dummy templates if that remains the current solution.
Thank you!
