It's super simple... Copy an image or text like normal.
Open the ClipHist GUI using Cmd+V (equivalent to Super+V, or Win+V).
Select the image or text and voila! A saved item was pasted!
Where did ClipHist come from? What purpose does it serve? Why not another application?
To understand ClipHist's purpose, it helps to know a little about my journey too. I previously used Windows OS as my primary operating system. Due to increasing frustrations with Microsoft's online account requirements, privacy violations, and general lack of control, I chose to switch to Linux. With Linux, I found a beautiful OS that is simple, straight-forward, and highly customizable. However, Linux has a shortcoming; since it is free of bloat, Linux sometimes lacks features that a given user may consider critical to how they use their machine. For me, this mission-critical feature was an equivalent for Windows' “Clipboard History” feature.
I tried CopyQ, Diodon, GPaste, Klipper, and Clipman. None of these apps quite did it for me. For me, they were either too feature rich (yes, that is a thing), felt non-intuitive, or just didn't mesh well with my workflow. That being said, I do highly recommend giving them a try as they may just work well for you and they are quality apps.
Since none of the existing apps seemed to meet my needs, I chose to design my own; Something super simple, lightweight, and as intuitive as possible. The result: ClipHist.
