I asked A!K Research Labs about this, because it looks so close to their program Notesholder Lite
. If I understand their e-mail correctly, QuotePad is a rebranding experiment of Notesholder Lite. I haven't tried it yet, but if the screenshot is anything to go by, some people may prefer QuotePad's permanent filter box.
I am a registered user of Notesholder Pro. Don't like the alarm system of either version much, but otherwise they're nice. Main advantage of Pro over Lite is being able to have categories of notes - sort of parallel ribbons. You can install both Lite and Pro as portable. Main disadvantage of Pro is, last time I tried it via a USB stick at work, Trend OfficeScan deleted it, yet another false positive
Lite is OK, though.
BTW you don't have to make Notesholder dock to the screen edge, you can hide that and just us hotkeys. I don't know why they add an extra hotkey slot ot hide the program, just pressing the "new note" hotkey twice or Esc once does just as well.
