I've noticed latency on opening vs some other tools I've used that are almost instant on showing up. I'd love to see the clipboard preview panel as staying maybe hidden and toggling show instead of having to reopen or whatever you could do to boost the startup and show when toggling it.

I am using the 5.0 release, and I have noticed quite a bit of lag in showing the Clipboard Manager the first time I use it in a while. After that initial startup period, it seems to be pretty quick to show itself again.
