@lazykid34 Do you mean assigning the command to a mouse button or having clickable button/icon displayed on the screen?
The first option belongs to request https://forum.obsidian.md/t/mouse-hotkeys/11013/2 (Which also describes current workaround / solution. More testing and feedback is welcome).
The second option (buttons on the screen) was implemented in https://forum.obsidian.md/t/obsidian-release-v0-8-13/5384
We’ve added buttons for navigating backward/forward on the top left of the app.
There is also a plugin to show history of recently active/opened notes: Recent Files List Plugin
