I'd like to echo miksh's 2nd suggestion:
2. When an error/warning is double clicked the file in question is opened, JustCode scrolls the error list to the top so it's quite inconvenient to analyze errors especially if there are a lot of them.
JustCode found almost 400 warnings in a large solution I'm working on and I'd love to go through them, but every time I double-click one the list list jumps to the top again, making me lose where I was. Which is terribly inconvenient... This still occurs with the "release" version of JustCode.
