Eboostr should support for fast or how deep it should go when making the cach file. So like, if I just want it setup for caching on the fly (fast) it would do so with out taking as much time, just caching the boot and other system files, also usefull with small cach devices. Like wise, I should be able to do a deep scan cach for when I have some time on my hands, a semi big device(s), and want the most out of what I have on my system.
Last I think you should be able to select witch device should get more of cached data, so like if you have to move a flash drive around, you can with out lossing as much data... Aka, 2 devices, a 2gb and a 4gb flash drive. The 2GB flash drive (witch is slower) should hold most of the cach file or be selected untill full to hold most of the cach file so that way I could use the 4Gb (witch is faster then the 2GB) for moving other data around when I need to.
Last I would like see it only use what it needs instead of deditcating a guess as to how much it will actully fill/use. Kinda like what MS does with pagefile.
