Thanks for the list. Regarding screenshots, I like macOS' built-in screenshot keybindings:
Command+Shift 3: Captures the entire screen.
Command+Shift 4: Captures a specific region (You have to select the area each time).
Command+Shift 4, Space: Captures a specific window.
Command+Shift 5: Captures a specific region (Remembers the last selected region).
Command+Shift 5 also displays a menu at the bottom of the screen that lets you select any of the screenshot options as well as options to record a specific window or the entire screen.
