For something lightweight and with a native look on Mac, I use http://mmattozzi.github.io/cocoa-rest-client/ Only HTTP/Rest but that's all I need.

First time I hear of Actual Budget, will have a look.

On very old Macs, the files did not actually move! Just a flag on file metadata. IIRC, it was System 7 that introduced the Desktop folder.

I know things have become much more complicated, but still remember fondly the good intentions of the original USB spec, which, for instances, forbade any extension cables (ignored, as expected, by many), with the reasoning that users should expect that if a cable connects, it should just work. Longer cables would need to be electrically "better", and extensions would eventually cause issues with electrical paths that were too long.

People still remembered the "black art" involved with, e.g., SCSI cables, where long chains would often had issues, and wanted to avoid that.
