Adminmenu Customlink Filename
I just used your plugin, trying to generate the basics for a new plugin.
When looking at the generated files I realized that in info.xml the Filename under Adminmenu has the .tpl file mentioned in the configuration (templates/templatefile.tpl). The documentation of JTL says that in Filename we should put the respective .php File (https://jtl-devguide.readthedocs.io/projects/jtl-shop/de/latest/shop_plugins/infoxml.html#adminmenu)
When adding a .php File to the structure manually and putting that .php File in info.xml to replace the .tpl, the template File is not being called anymore when accessing the admin Functionality of the Plugin.
How to get around the issue? Can that behaviour be corrected manually? Which file has then to go where and how to get the template file working together with the .php File?
