Hi,
I just tryied your plugin and it is suprisingly awesome: the screenshots are perfects. Congrats.
I see no annoying client creating PR on default parameters as every good project has. So I give it a go.
If no output is specified, you use stdout perfect.
May we (you, I) add that if no target is specified, the full window of the current section is used so the test command reduces to tmux2html
Thanks for the awesome plugin, easy to install.
