Hi
I have seen in other threads people asking if it is possible to automate repetetive tasks in Calibre. I will also admit to being one of them.
I did a few desultory searches for Windows macro creators but did not find anything that really looked as though it would do the job.
As an automating Calibre thread came up again a few days ago I did another search and found a freeware program that impressed me and will do the job.
It is called "Pulovers Macro Creator".
I have had a little play with it and found picking up the basics not too bad. There are tutorials, walkthroughs and set of video turorials online.
I will let you know how I get on with it
