Version 1.4.0.0 was released on 03/14/2021. Notice that this version was not tested, so it may cause error while using it. If this occurs, please install Metro Callouts 3 v1.3.0.1.
This is my first plugin for LSPDFR. This project was started on september 2018 and the last stable version was released on summer 2019, so the code can be improved. If you feel like doing it, commit a pull request for it.
