Dear Developers,

There are some little, but useful improvements: :-)
- In left tree, left click on a table, and select 'view filtered data'. 
Can be set to focus to the filter text input?
- In left tree, left click on a table, and select 'view data', and 
select 'sort/filter option' icon. 'Data  sorting' tab.
If there are more than 1 sorting column in the list -> You press 
'remove' button. It is remove the selected item from the list, but not 
select the next item in the list.

Best Regards,
   Ferenc Lutischan
