I work with 6-10 different database connections pretty much all the time and within each connection for a describe window I will have 6-10 different objects I am viewing. So there are 2 different features I would like you to consider:
1. for the buttons I realize you have the color option and the connection bar ordering which I really love and in fact I believe I was partially responsible for that enhancement. But what I would also like to see is the ability to replace the button title like "Editor", "Schema Browser" and "Describe Objects" with the database name and/or alias for the given connection. IMO the icons clearly show you the type of window but when you have 20-30 of them across the screen it is hard to tell for which connection each button is associated. If I could label each button with the associated DB that would be great and make it much easier when switching between instances.
2. For describe windows I would like to be able to remove the schema name from the tab title. I thought there was an option already to not display the schema name but I must be thinking of something else. Anyway I am always working within the same schema for a given connection so having the schema name on every tab is redundant and just clutters things up. That and/or if you could have a multi-line tab bar like you do in schema browser that would also be nice.
