TmuxRunner

The plugin gets triggered by the word tmux. After that you can search for a session. If the name does not exist it shows an option to create a new session with the specified name. After the name you can add the initial path. But instead of typing out frequently used paths you can use the shortcuts: Each shortcut has to start with a $ and gets replaced with the value. You can use absolute paths and relative ones, but if you want to reference a directory in your home folder you can just type the folder name. For example Downloads/Bluetooth gets interpreted as /home/USER/Downloads/Bluetooth.
Shortcuts can be created/deleted in the config dialog.

Furthermore you can change the terminal you want tmux to be launched in. The default options are: Konsole, Yakuake, Terminator and Simple Terminal. You can also define a custom terminal. In case you want to use one terminal emulator for the mist time and another sometimes you can set one as default and select the other for the action (like instance Yakuake in the config screenshot). Now you can switch between these two the terminals just by Enter(default) or Shift+Enter(action).

If you want to change the terminal for just one command you can add a flag to the end of the statement. The flags start with a - and is followed by the lowercase start letter if the option. For example -y opens it in Yakuake and -c opens it with your custom terminal.

The option "Show create options for partly matches" allows you to create a session even if any existing session starts with the query.

Additionally this plugin supports tmuxinator by letting you create new sessions with parameters/options and attach to existing. You can also combine this with the terminal flags as explained above.
