Admin panel updates. Please, guide me.

I am using Opencart - v1.2.6

I would like to change a few things in the admin panel. When you edit/add a product I would like to make the textarea for the category's longer. Which template file contains the html to update this?

I would like to change the home page in the Orders tab, I would like to add the order status to see if the payment has been completed or still pending on payment.

Any help in pointing out the files these are in so I can edit them. I have spent almost 2 hrs trying to find the files in the /admin folder.

1. Version 1.2.5 was released today!
2. All template files are located in -> ../admin / view / template or the controller files in ../admin
3. It should, however, a few files be changed to realize this.

I made a mistake it was v1.2.5 that I am using.

Well, yes, thanks, but was looking for the file these were in. Still have not found which file to edit.
