So, this morning, just a handful of days after the last release, there's yet another App Inventor release (dated July 25, 2011). It's mostly bug fixes, but there are a couple of neat new features on the TextBox component I need to mention.
First, is the Multiline property for TextBox. You'll find it in the Properties column in Design whenever a TextBox is selected, as shown in the next screenshot. In the associated drawer created in the My Blocks tab in the Blocks Editor, there's also a block now letting us set the number of lines we wish the textbox to display. This is something quite a few people have asked the developers for.
Also, something else has been added that fixes a problem annoying many, including me. Before this new block, also in the TextBox drawer in Blocks Editor, when the user tapped the textbox and entered some text and clicked a button to save it or otherwise do something with the input, the phone's pop-up keyboard remained in place. Now, just add the block...
