Cons

Con A little slow
Similar to Spectacle, but it has a few more features, such as being able to pick the size adjustment increments. Spectacle was a little faster, though. Repeated size changes or moves in succession can cause it to wait for it to complete.

Con Imprecise when readjusting sizes
Con Doesn't support moving windows between workspaces
There's no way to move a window to a different workspace with hotkeys in ShiftIt.
Con Crashes constantly
Crashes when working with mysql 8.0.12 for macos 10.13. Unable to do anything.
Con Not maintained
The app crashes when you close a tab.
Con No MySQL 8 support
Con Not adapted for MacOS Catalina
Con No multiple query tabs
Sequel Pro does not support multiple query tabs in its editor. This is incredibly frustrating for a power user.
Con Text in the query lost on connection failure & crashes
Con OS X only, no Linux or Windows versions
Power users have to manage in many different environments. A consistent admin interface is hugely beneficial.
Con Query editing capabilities much poorer than MySql Workbench, Querious, and others
Con No visual query editor
Con Unable to import from binary SQL files
I frequently import binary multipolygon data from another source, and it won’t open.
