What are some alternatives?
Gis.XL - Online maps in Excel
SizeUp - SizeUp allows you to quickly resize and position your windows with keyboard shortcuts or a handy menu bar icon. Arranging windows on Mac OS X is tedious and imprecise.
Spreadsheet.com - Spreadsheets that come alive as applications
Hammerspoon - This is a tool for powerful automation of OS X.
Airtable - Airtable works like a spreadsheet but gives you the power of a database to organize anything. Sign up for free.
Moom - Move your mouse over the green zoom button in any window, and Moom's mouse control overlay will appear (as seen in the above animation).
