Maximize predictive word bar space
The TW logo(settings)/language indicator take up precious space on the predictive word bar.
Not my place to suggest loosing the logo advertising but the UI would look a lot cleaner imo if a simple "gear" symbol (using a less obtrusive contrasting foreground color against the existing background) is placed somewhere in the unused layout space e.g. to the right of the ?! key and the language indicator in the upper left corner below the now maximized predictive word bar.
