Feature request - caching icons

Hello and sorry for such a small request.
Is it possible to add an option to store app icons in persistent cache? Persistent between reboots, so the only time it would read icon from program's exe would be when you clear that cache or a new program is added into TLB's menus.

My reason is: when my computer starts, TLB starts reading icons from all those programs which I have in menus, and with a lot of items (hundreds) it can take pretty long time. Windows explorer process is frozen during this scan, so usually I go drink some coffee.

Or, maybe an option to read icons when they are needed (menu containing them is opened)

p.s. My PC is about 3 yrs old, but it's fast enough for me so I'd like to avoid unnecessary upgrades

I plan to make the something like icons cache.

Or, maybe an option to read icons when they are needed (menu containing them is opened)

The virtual folders have the same feature. TLB loads the content of the virtual folder on first open (including the icons).
