Loving it so far. Would love to get an autosave feature and/or group changes as in workona or simple tab groups.

Excellent extension. This extension along with "Switch to Previous Active Tab" make Firefox the best browser.

Muito útil para organizar pesquisas, referências e muito mais. Indispensável para manter-se organizado e com as listas de leitura em dia.

All functions working and it's so good, I seen this idea many time but this extension have the best implementation of the idea so far.
