I am obsessed with Alfred's clipboard history, it's quick raw extremely reliable and extremely functional form factor and versatility. My concern is that I use it as a replacement for reminders/note keeping as it's way more convenient to quickly type something and copy it, then later when need to recall it, simply search based on specific reminding characters.
The problem is that this only remains available for only three months and that's extremely unfortunate. I also use BetterTouchTools on my Mac and they offer clipboard history to remain for up to one year, but the form factor just isn't as convenient as Alfred since Alfred just offers more.
I am aware that memory management might the reason why it's capped to three months, but I only use it for text, and have disable it for images and files, so maybe that should make it a but more manageable, especially since BTT's clipboard offers it with no issues.
