So right now the preview window of the clipboard allows you to see enough to know what's in the entry, but it's not so great for consultation.
For example what I often do is that I copy bits of code that I only want to use as reference, but since reading those in clipboard preview is difficult (small text, broken lines, etc) I'm forced to paste the contents somewhere else.
So my feature request would be to be able to customize the preview window (larger space, larger text) or simply make it bigger by default.
