To edit the note, just select the task "StickIt" in the task manager. You can update the text manually using the More->Update command, however the text is automatically updated in each second.
You can turn off the note visibility in the standby screen using More->Toggle visibility->In standby or you can show it in the app as well (as a preview) using More->Toggle visibility->Here. To change the size and position of the note select More->Un/lock. When in unlocked mode, a titlebar is shown as well as the resizing corner. Grab them to move around or to resize the note. Please note that when in unlocked mode, less text is visible.
