Just downloaded and installed Superlauncher, regular 30$, free on giveawayoftheday TODAY ONLY (up to 10 o'clock tomorrow morning, seen from Old Europe).
No help file, prefigured short keys to some system folders and so on, possible to enter files or folders, manually (only?) into the list, list available from symbol in the notification area (only?), didn't find a hotkey to launch the launcher, but there very probably is one.
It does not seem to be possible to have it as a vertical ribbon (?). Does anyone use it? Judging from its price, it should be as good as some described in this thread, but it seems to be far behind, but then, I could be mistaken; as said, I did not see any help file for it. Probably download/install today isn't that a bad idea if someone comes with more specific information even later on (install needed within the downloading timeframe, but I suppose you know that).
