[Suggestion] Few things for template replacement window

[rhoun]

A few improvements to the current UI:

1. Please add the ability to collapse groups like in the train window for the template replacement window. When you have many groups, it's pretty hard to navigate it. My scroll handle gets smaller and smaller with every new group, see the image below.
2. Shorten the 'Template in use' to just 'In use' and move it to the same line with the price. Now it makes hard to see what loco is in the template.

Now, here are some random thoughts; it's more to think about than a suggestion, but two things will improve templates even further:

1. Names for templates, possibly limited in length. When a template has a name, display it instead of 'template in use:' in the groups list.
2. One-level groups for templates itself, just to organize the library of templates.

You can already name templates. This is what the rename button is for at the bottom right.
The gap after the cost is for the name to go in.
