1 thing I have noticed with Titan is that there seems to be quite a delay (up to 10secs) from when I click on say "Movies" till it shows up the "Movies" page with the DVD on it. During this time, it has the Titan background, just empty. However, this only occurs on the first time after starting Kodi. When I go back to the menu and click again, it is almost instantaneous.

Is there anything that I can do to make it quicker like disabling other themes etc.

That's because Titan has a lot of views you can choose from. While this makes the skin very versatile it also slows the skin down on slower devices.
At first load of a section (movies, tvshows, music etc.) Kodi will load all the related skin files. So for the movies section it will load all available views as xml files into memory. That takes processing power. On a very powerfull machine you won't even notice that but on slower devices this can take several seconds.

A very good way of solving this is disabling all the views you never use. Especially the more heavy ones like power row and showcase.
You can disable views in the skin settings --> forced views --> all the way at the top,

I thought this was a very good suggestion. I didn't even know the setting existed. I just tried unchecking every view except horizontal, the only one I use. I went to browse the library. It won't budge until the drive(s) spin -up. I can hear the drive spinning up while it's stalled. Once the drive has spun-up, I can navigate..... until I come upon a title that resides on another drive that has not spun up yet. Once it too spins up, I can resume navigating until I come upon yet another drive containing that metadata and have to wait again. Attempting to navigate by holding down the scroll results in a crash every time. Again, I don't know if it's just my system or if this is prevalent for everyone.
