I've made a github repo with live templates and files templates to use in PyCharm.
This was inspired by the vscode plone addon : GitHub - plone/plone-vs-snippets: Visual Studio Code Snippets
Here is the link : GitHub - jihaisse/plone-pycharm
Note that I am still using Plone 4, so, some live templates (like behaviors) are in Plone 4 style.
I wanted to add the repo in the plone github, but I am not allowed to create a new project inside.
Anyway, you are welcome to contribute.
