Hey all, I've put in a couple of tickets hoping to get the user experience improved on Mac OS X.
http://www.jetbrains.net/jira/browse/IDEA-23184 - Always on top detachable windows doesn't make sense on MacOS.
http://www.jetbrains.net/jira/browse/IDEA-23185 - Horizontal scrollbar should always display on OS X
http://www.jetbrains.net/jira/browse/IDEA-22795 - Help menu opens very slowly on OS 10.5
http://www.jetbrains.net/jira/browse/IDEA-23232 - Use system color picker instead of custom color picker.
Plus there is the already existing:
http://www.jetbrains.net/jira/browse/IDEABKL-67 - To allow multiple editor windows
http://www.jetbrains.net/jira/browse/IDEABKL-2861 - To use Mac OS X file system dialogs
Any votes would be appreciated.
