The app is a good tool for you to monitor websites, price updates and etc... but it needs some adjustments and refinements.Some pages need more time to load all the items and boxes and the Web Alert App doesn't wait for this pages to load correctly. So the page selection that I choose cames wrong and makes impossible to properly select the area. Another cons of the app is the computer power to run it. Sometimes when the app is running in background it really makes the Mac slow and turn impossible to leave it running this way, so I close the app and continue doing my stuff on the computer. Maybe this pages selection analysis shoud run on an server and not on the computer, this would solve the CPU power and memory consuption.The app shoud let me edit the page selection again after I submit the alert, not just edit the name of the alert. Sometimes the websites changes the area that I chosed and I can't do a new selection, I just creat a new alert with the same page. And for last, would be good if the app keep all the history of page changes not just show the two options "previous selection" and "updated selection". This selection changes history is good when is about price changes etc.Keep up the good work Denk, your app is awesome.

"notify each time the selection uptades" doesnt work in macos last version and macbook air 2015.
