Not great, clunky way to activate (why do you have to keep right click and spamming), tree re-planting does not work properly (also doesn't even try to account for 2 by 2 trees like dark oak, jungle, spruce, etc.), and its algorithm for detecting "trees" is often wrong (like on large oak trees).
A newer version (2.3.0) is now available. This solves the clucky way to activate, adds a new option to keep the tool activated. Also you can disable the whole activation/deactivation message. Also support for 2x2 trees has been added!
