I've released version 0.2 of SlushMiner on my SourceForge (https://sourceforge.net/projects/slushminer) with some big backend changes and a few interface improvements:

• The backend code has been completely restructured, making it much easier to maintain and allowing me to release the source code without making myself look bad The source isn't quite ready yet, I need to clean up and comment everything but once it's uploaded I'll post here
• Worker information can be manually overridden in case Slush's Pool website goes down (like it has been lately). He's got mining working but the site itself is down, so this will allow SlushMiner to work without the login
• A new Charts tab with line charts for hashrate, share rates, and rejection rate
• Automatic new version checking (disabled by default, you can turn this on in the Settings tab)
• Custom refresh intervals for miner program, currency markets, and pool stats

There's a few other smaller improvements, you can find them on my website. Let me know what you think!
