We can do it directory wise. Or (I haven't looked at the code so I don't know if this makes sense) we could increase the functionality of the tile loader. The current tile loader stays at it is but it get's an additional functionality, where it passes the names of the tiles that it's going to load in the future to the terrasync thread (i.e. we specify two ranges - the frist as we do it already with says which tiles we want in the memory and a second, bigger, range for tiles that are probable to be loaded soon). > That means I probably means I'm not going to have time to do it, so > bear in mind that this discussion is going into a black hole unless > someone else picks up the slack and has time to continue developing > this. I know that problem... Probably it's time to thank you for your effords again (we can't do that often engouh...)
