With this edit field you can affect the size of the caches. You can input a percentage value up to 100. This value always refers to the current optimum size that can be displayed in the Navigator bar. A value of 100 % means therefore that the caches are held 1:1 in this optimum size in memory. If the value is lower, then the cache size (and memory requirement) is also smaller – but the graphics displayed in the Navigator bar also become coarser, i.e. less detailed.
