When there are multiple links, Hover on link to preview linked notes
Support for 'mouse Forward/Backward buttons' - To move between current-previous notes, similar to webpage in a browser
if that'd interfere with Obsidian's own support to navigate current page, configuring it to hold-Shift+click, or something similar would help.
Keyboard navigation should be supported as well. perhaps Alt+Left/Right-arrow ?

Since double-clicking on a note in Canvas automatically zooms into it for visibility, which is handy, there should be an easy way to zoom out as well. like 'Esc' as a keyboard shortcut which takes you to 100% zoom.
