So, I sort of answered my own question :
I created a half-assed template by creating a new entry, rearranging the fields to my liking, and adding a single character to the title in order to enable it to be saved. Then, when I need to create a new entry, I right click and 'Duplicate' to reproduce the "template". This works only with manually added records of course.
I wish I could just right click on a Category name and have some options to delete, edit, rename, etc.
I guess the developers are too busy with their day jobs to respond to something so obvious.
