Use black colored action icons instead of gray and use black for a populated note icon
For most software, gray is the standard color used to indicate that an action is NOT available, but Todiost uses gray for every action icon. My brain tends to ignore gray on the screen, so, when I see a gray icon on Todiost, it takes extra effort to switch my thinking for the anomaly. It would be better that the action icons were black instead of gray.
Also, the note icon is gray whether or not there is a note. If black were used when there is a note then it would a provide faster way for my brain to confirm a note is there instead of double-checking if it is a pop up because I am hovering my mouse there. I know a number shows, but it requires extra brain processing and mouse movement to observe.
