The formatting aspects[Bold, Italic, Bullet etc] in the description window of the task box are at the bottom. If the description is really large, then one has to keep scrolling to the bottom frequently to select a particular formatting feature.
In fact, this window is a good example, where such aspects can be fixed to the top of the page. And shouldn’t disappear even when the description is too long. [ Something like Freeze view in spreadsheets]
