view: Add @thumbs-contrast option
Add an option to surround the hint character with square brackets (for example `[a]` rather than `a`). This is the equivalent to the following `tmux-fingers` configuration option [1] and is useful to make the hint more visible: ``` set -g @fingers-compact-hints 0 ``` [1] - https://github.com/Morantron/tmux-fingers#fingers-compact-hints Signed-off-by: James O.
