I've written a tmux-plugin-manager to replace tpm
(supports only tmux 1.9+ among other problems). It uses part of the ellipsis src files and is build in the same way. It can be installed with ellipsis and i've called it ellipsis-tpm. It's currently in an early alpha stage (more a proof of concept at the moment, low code quality in some places) would you mind if i further developed it under the ellipsis org? I also think ellipsis and ellipsis-tpm could share more code in the future with minor changes in the ellipsis source here and there.. :) if the project evolves well i might also at plugin/package managers for other tools.
