Been using this for a long time whenever I need to remove a background. It used to be more unique, and a lot of other apps are out there now, but this has stuck with me cause it gets the job done.
I think that SigmaOS broke way too many patterns of existing browsers and overall made the UX worse. This was especially pronounced in its use of hotkeys and shortcuts in general. With the way so many patterns were changed, it felt like a"if it ain't broke, don't fix it" type of situation.
I only used this app for about a week, but it was awesome while it lasted. Only reason I stopped is because my team stopped using Linear and transitioned to Asana which lacked an integration.
