# Next TODO:
# Server configurations:
#   - where do we store it?
#   - TOML? yes probably toml

# * Quickpanel for connecting with stuff.
# * Quickpanel for browsing the servers
# * Move all "server actions" like, create, delete, rename etc. as quickpanel actions. (See SFTP plugin.)
# * make panel for notifications!
# * make panel for errors and logging!

# Proxy Commands ( NOT USED, left just in case we need it again. )
