I have two questions:

1. Why when i enter in the schema editor to the table list, the application freezes for a couple of seconds(~15s) and the it shows the tables list?
2. When i double click a table in the schema editor in order to open the data editor, it also freezes for a couple of seconds, how can i limit amount of rows so it's not that slow?

I'm using the version 9.1.4 in ubuntu 16.04
