Hi, i cant find the extension in aseprite?
If double clicking the file didn't work you can go to Edit / Preferences / Extensions then click where it says add extension and find where you downloaded it.
oh i mean its installed in the extensions tab, but i cant find the actual tool in aseprite under the edit tab. sorry for the confusion
What is your aseprite version?
Updated to 1.3 Beta, is working now!
