I think it would be beneficial to be able to assign a specific height or even a minimum height to one or modules. Right now, you can only do the width. This will come in handy when you are using multiple modules side by side and want to make sure that they are even in height, regardless of the content. In my case, I had four modules side by side. I edited the template.css file and added a min-height to each class selector for that module. But it would be easier to do it through Template Toaster. It should also take into account the amount of content in each module so that each module is the height of the module with the longest content (i.e. the min-height would increase as needed).
