What is making my cursor 'randomly' disappear when using gnome-teminal?
You may have inadvertently hit the VT220 escape sequence to hide the cursor. If so, then neither Ctrl+Q, nor reset, nor clear, nor Ctrl+L will help.

Make kitty terminal emulator to use the current working directory for new windows
In your kitty.conf, instead of using map ctrl+shift+enter new_window, use map ctrl+shift+enter new_window_with_cwd.
Couldn't find this in the documentation but the author mentions it in this issue.
