suggestion

select field_with_very_long_text from table;

ok, hsql shows me all it can in one row, I want to see it all - clicking button at the end of row which apears when editing is possible .

Can't coz it breaks with "Selected column ..... to alow editing"

I think mybe that we should be able to see whole contence despite it can't be edited.

button in cell should be enabled prior to warning about not able to edit.
