I was sure busybox can't be uninstalled without having much problems. Anyway, I installed new althist and it works greatly! Thanks a lot! Now waiting for it to be released under repos, as I have CSSU Thumb.
Today I found another bug. In my MyDocs/.videos I have a directory named in russian letters (well, I guess any non-english letters will do the trick). Now, I start typing in x-term the command: ~ $ MyDocs/.videos/ Then I press TAB to take a look at the suggestions. As I have there only one directory, ash (or busybox?) substirutes it to my input. But if I only press TAB one more or twice times, all the command goes away! Is this a bug of busybox-power, or ash? I didn't notice anything similar before installing busybox-power-althist, but maybe that can be Thumb tree bug: I installed that just before busybox-power.
