Theme Trouble Shooting
1) The "Find" feature appears to be hidden behind the status bar.
When switching themes in Sublime Text, it will retain the height for the Find bar set in the previous theme. Sometimes this will cause the bar to appear hidden behind the status bar.
To fix, simply grab the bar and pull-up.
Installing and switching themes in Sublime Text may cause some sidebar icons to not show. Removing or disabling themes no longer in use, typically ones that have their own custom sidebar icons, should fix the issue.
