support for several logos
Right now it's possible to only include exactly one logo into a beamer presentation template. In reality, people often use several logos, e.g., the one of their university, of the project they're sponsored by, and so forth. Also, one institution might have several logos to be placed, e.g., an actual logo at the top and some sort of mission statement at the bottom of the page.
I believe it would enhance beamer to have support for this.
