So question is, did I need to install Marcel's repository first or should it all have been automatic? Just asking before I upgrade my ODroid to Matrix. 

PS a skin restore partially got my heavily customised look and feel back but I'll have to redo all the widgets and stuff. Still, a lot better than completely starting from scratch!

For Titan-Mod Matrix you only need the "Fuchs-Repo" 
SHS is automatically installed.

If you want to keep the look of your Leia-Version, use "Manage Color Themes".
Save your theme and import It to the Matrix version.

Widgets and menus must be adapted.

A reinstallation is better, you avoid mistakes.
Auto Update does not work if the Skin or SHS was manually installed.

Thank you.

I bit the bullet and uplifted my Odroid N2 to Matrix. But this time, having learnt from my Vero install, I was more thorough in removing all remnants of Titan and dependencies. The Titan Matrix install was then flawless and worked first time. Restored my skin settings from backup and a little tweaking of widgets & I am a happy bunny

On possible issue I have spotted with the Matrix version, the Spotlight widget is quite slow compared to Leia. It takes a few seconds to even minutes for the artwork to appear. Particularly apparent with Random Movies  and less so with Random TV Shows but definitely there. Happens on both my ODroid and Vero. Not a huge issue but would be great if you could look at. Once again, many, many thanks for the superb work!

Edit: Played around and some more info on the above. I am using the Enhanced Home Screen. Issue happens when I switch from one menu to another and back. Eg, Movies->TV Shows->Movies. Or go into Movies and back to Home Screen.  Spotlight widget takes ages to show artwork. I can get it back by navigating to it etc but moving back to the bottom main main mune makes it disappear again.
