# THEME
#################################################

# Design rationale:
# - Basics: visible windows tabs, active one highlighted.
# - This follows the look-n-feel of my generic theming (vim, kakoune, liquidprompt, etc.).
# - Blue is "insert mode", i.e. what you type is typed.
# - Yellow is "normal mode", i.e. the item is a (potential) target for a command.
# - When entering prefix, the active window tab is in yellow.
# - Tabs structure: <window number>(<activity marker><number of panes>)<window position> <window name>
#     - the activity marker is a ‼ if there is a bell alert, a ! if there is a silent notification, a ∘ else.
#     - the window position is a dark ⁚ for the active window, a ⁝ for the last window and a light ⁚ for others.
# - When entering prefix, a yellow [A] is displayed and the active window tab is yellow, drawing attention to what you are doing next.
#
# NOTE: needs Powerline symbols (use a Nerd Font).

# Just like a normal window title bar.
