Thank-you for creating DBeaver, it's really good!
I would like to suggest the following:
+ Alphabetical sorting of table columns (eg in the query editor 'WHERE conditions' and in the database navigator tree).
+ Quick table/object filter in the database navigator panel (a text box under the tab, rather than having to bring up a dialogue). This would jump you to the first match and then the next match in the navigator panel, it wouldn't hide anything.
+ The ability to import a CSV directly into the results window (like MySQL workbench supports).
+ Colouring or shading or the 'Explain Plan, 'Execution Log' and 'Output' tabs to more easily distinguish them from multiple result set tabs.
+ The ability to 'rotate' the result set, so columns become rows and rows become columns. This isn't a feature I've seen anywhere else before, but would be useful when trying to scroll down the values of a small number of records.
Thanks!
