Can I suggest that fasm implements ability to see what .asm source is used in the editor by holding the mouse over the icon on the taskbar, sometimes I have 3 copies of the editor running at the same time and all of them may have many tabs open. But can you make it so that when you hover over it, it will display the .asm file whichever is currently active in the current tab?

Because windows rotates the order of the icons in whichever order you use them most frequently, making it less user friendly to find the icon you want to use. I have become the best guesser in the world after some use of this, I have learned to guess right, but I am tired of guessing
