Hi, i am developing a plugin to use with a custom language. I need to open a proyect written in that language so i need to perform a few actions after i select a proyect file when i click on the "File -> Open file" menu (this file has a particular extension, .list in this case). Is that possible? or i need to make a custom menu? In that case, what is the menu path for inserting a menu in the "File" menu? Thanks
