# --- Plugins ---
# TPM
set -g @plugin 'tmux-plugins/tpm' # TPM itself (tmux plugin manager)

# General
set -g @plugin 'tmux-plugins/tmux-sensible' # It tweaks a few default settings I wouldn't know to change otherwise.
set -g @plugin 'niqodea/tmux-matryoshka' # Makes nested tmux actually work


# Session management
set -g @plugin 'omerxx/tmux-sessionx' # Session manager
set -g @plugin 'tmux-plugins/tmux-resurrect' # Allows tmux environments to be saved and restored via prefix Ctrl+s and Ctrl+r
# I would also like to look into stuff like nvim session restoration: https://github.com/tmux-plugins/tmux-resurrect
set -g @plugin 'tmux-plugins/tmux-continuum' # Automatically saves with ^ every 15 minutes, and restores on tmux server start.
# Restore tmux environment on server start
set -g @continuum-restore 'on'
# Note: 
# > In order to be executed periodically, the plugin updates the status-right tmux variable. 
# > In case some plugin (usually themes) overwrites the status-right variable, the autosave feature stops working. 
# > To fix this issue, place the plugin last in the TPM plugins list.
# Keeping this in mind, in case I have issues.

# Appearance

# Actually runs all the tmux plugin manager things
