Estel: Yeah I know this is just as reliable as xxxpatch users' testimonies, but do me and yourself a favour: close all microB windows, click on microB and watch the time, takes around 0.5 second for the bookmark window to open up. Move microb-engine to opt, repeat the above, starts instantly. As startup loss of half a second is not even worth arguing about random read/writes etc. doesn't matter as it is not random but ~5MB worth of read/decompression. It does visually for me take more time to start and for you most likely also will. Lets not argue about non-issues.
