Paint's journey has been so weird. It was going to be replaced by Paint 3D, made an optional component, and now it's getting updates I would have killed to have 20 years ago. But it's been such a useful and enduring tool because of both its ubiquity and its simplicity, so I hope the upcoming changes will be as minimalist as those of the past.
Considering how slow the new calculator app is, I am terrified of Microsoft updating the classics. These things used to open instantly and provide value. Now it is a visible pause and gigantic white space heavy interfaces.
Is it? Just opened it on Windows 10 and it opens instantly and uses 23MB of RAM which is rather low for a modern application. Calculator is also fully open source now.
