I use the "Found Image" in almost every macro, and there's a few features that would save me a lot of time when building macros.
Screen Capture. Give me the option to grab a portion of the screen right from within the action editor. Instead of use the system screen capture, then save the image, locate it, and drag it onto the square, imagine how fast it could be if I could just click a button, have the rectangular marquee selection tool come up, and have the captured image go directly into the action. No saving, finding, dragging.
Allow me to open a file selection dialog right from the "Found Image" action to browse for an image instead of having to drag it there.
These two features would greatly speed up building of macros that use lots of "Found Image" triggers.
I use the macOS ββ§β4 keyboard shortcut to save the screenshot directly to the system clipboard, then paste it with βV into the image well for the KM action. This is pretty speedy for me. This method is also generally the more reliable for KM to find the image. The wiki page has more details https://wiki.keyboardmaestro.com/Found_Image
Iβm not sure if it would make things more cumbersome, butβ¦ I had an issue with being able to find an image on a screen where the text and the background were not too far apart in color - low contrast - so I adjusted the contrast in the image I added to search for and that fixed it. So might be nice to have some simple processing tools present for the image in a pop up or something.
There is a whole slew of these that have been here since OS8 or 9 that haven't changes. When they first went to OSX they were missing but came back right away. Control+command+shift+4 is so engranded my fingers at this point with another shortcut I do on average a dozen or so times a day.
I don't know when Windows "Was snuck into these shortcuts" but just noticed that when I took a screenshot.
