[FEATURE] Lots of tables cause dragging lag

[yao-1212]

15 tables with two dozen fields each, even 30 in some cases, and dragging is too laggy to operate at all.
Maybe there's a problem with my database structure setup, but I don't want to modify the structure to be able to optimise this case of multiple tables dragging and dropping and lagging

nope the database structure is fine. the app just gets slow. for now you can turn off the sidebar until it's fixed

Same problem, hope it can be fixed ASAP
