I've been using CopyClip2 for years. I much prefer Alfred's clipboard manager except for one minor issue, paging through the result list. When I pull up the clipboard history, you have to scroll top to bottom. If you have a keyboard with page up / page down, this will work, but it's frustrating.
The simple solution should be to allow the use of left / right arrow keys to move forward one page, back one page in the clipboard history result list.
