A plea to Olympus: Exposure compenastion in manual mode on the E-M5

Generally speaking, in manual exposure mode, it's the photographer who has to make all the changes to set the exposure he/she wants. There's no exposure compensation per se in manual exposure mode. Exposure compensation is for you to overide the exposure settings decided by the camera when in auto exposure mode. Since that's not the case when a photographer is using manual mode, there is no need to have an exposure compensation setting button. After all, changing the expsoure in manual mode is just as easy as turing an exposure compensation
dial. You have to turn a dial or press a button one way or another.
