I have noticed that many dialogs do not open at a size or ratio that a person would want to see, requiring a resize. I really love that Spoon allows resizing of all dialogs. I just wish they would open at a size that is reasonable on modern displays.
See attached screenshot of database connection Feature List dialog when initially opened.
NOTE: This JIRA isn't only specific for the Feature List. This type of thing, while not as dramatic, exists throughout dialogs in Spoon.
It's great though that you can manually resize, but a tool this far along in development should have more polish for theses types of things.
