A small request re the Overview screen

If I select the overview screen from the hamburger menu it typically takes about 3 seconds (or thereabouts) to display the screen. However, if I return to the Overview screen via the back button ( < ) it’s pretty much instant - I’m guessing it pulls the page from a cache rather than creating it from scratch. I appreciate that selecting from the hamburger menu implies that you want the latest overview of your libray, but if you haven’t added anything since you were last looking at it, and it’s within a reasonably short time frame, wouldn’t it make sense to just pull the cached version rather than recreate it?
