Visual C#/Studio should have a global Resource file containing at least 1000 different icons, and at compile time only the icons actually used would be included. This would bring several advantages: a consistent look of the program/meaning of buttons for the user, and for the programmer the fact that they would not have to hunt for icons (which often come in different resolutions), they would know which icons are in the Resource file (I have ten thousand of these icons (though many of them are similar), but I have no idea at all which ones I have and which ones I don’t), right after installing the IDE they could start building visually polished programs (unless someone needs an outright coloring book), and they would not need to be at the PC they usually program on.
That said, I have not yet seen this in any program/IDE, so Visual Studio is certainly not lagging behind here…but why not be ahead? 🙂
