mem should be no prob, as nearly everyone has enough fastram... and it "only" eats 200kb chipmem.
Unfortunately, I don't have much RAM to spare. I've only got 8Mb Fast on my A500 and I like to open a couple filemanagers to view downloaded files/images or extract archives while browsing. If I open a couple 1Mb filemanagers, I'll run out of memory faster than a greased pig down a drainpipe.
Hey, I just noticed that MaxonTools2 has the "click on left or right border for parent" just like ABCdir and Ordering! Too bad it doesn't have ABCdir's "right button list scroll".
