What's new/fixed highlights

• New Icon
  The icon was always meant as a placeholder, but somehow (read: due to laziness) it managed to sneak into Beta 2.
  
  The new icon comes in a variety of sizes, 16x16, 32x32, 64x64 and 128x128. If there is demand, we can probably add higher resolutions as well down the track.
  
  
  
  The other fix involving icons is that the same icon will appear in the system tray, when you pin the app and when the app is running - previously some silly mistakes on my behalf meant that you were presented with an ugly "MT" when pinning.
  
  
• Global Exclusion Filter
  Don't you hate it when your social network fills up with updates about certain events you aren't at because you don't care about the event? With the global exclusion filter, add those terms or hashtags and they'll be removed from all columns.
  
  
  
• Search
  Either click a hashtag or the magnifying glass to bring up a new search column. It may look a little strange that you have to select 'Twitter Search' to be able to search, but in future updates this will include more search services like Twitter User Search, Facebook search, Flickr image search and more.
  
  Twitter Saved Searches and Twitter Streaming Search will appear soon!
  
  
  
• Scripting changes
  I can't do the list of scripting changes justice, but scripting filters are awesome - Two example filters are included, add/edit a column -> select show updates that have geocoding, and you'll get a column of updates that contain geodata. As this is could easily be changed to add extra data requirements like a certain number of hashtags or terms mentioned in the Tweet as well.
  
  
• Column Counters
  While we're not finalised on the UI for these yet, you'll notice the individual column counters have returned and are far more accurate than before.
  
  
• Clearing individual columns
  
  
  
• Drag and drop
  Like in MahTweets 2, you can drag contacts from column to column to quickly add them to your filters. Unlike MahTweets 2, however, you don't need to click a button first.

As usual, there are a fair few bug fixes and other hidden gems, but there are far too many to list or explain. If you're so inclined, check out the commit logs from Subversion from around 752 -> 799.
