Review for Multiple Addon Deactivator by bege1
Rated 4 out of 5 stars
After the developer fixed a serious bug this add-on works fine. Thank you to the developer. It is very helpful if you have many add-ons and want to test them. It replaces a very helpful feature of MrTech's Toolkit, which isn't being maintained any more.
I am curious about the planned new features, hopefully something like different profiles which allow to have different sets of add-ons activated with one click.
