We've made a small change to the way that you navigate between some of the activities on textivate.
The +tiles and -tiles buttons have gone and have been replaced by a drop-down box (see the image below).
This makes it easier to navigate directly to the number of tiles that you want to see in your activity.
These changes have been made to the following screens on the text side:
Tiles (all), Horizontal, Paragraphs, Next Word, 50:50, Initials, Empty, Anagrams
...and the following screens on the Match side:
Shuffle Match, Switch Match, Click Match (all), Memory (all)
