Search shortcut case sensitivity (manage search engines)

So many times, I use a search shortcut that I created, and it doesn’t work. Instead it does a web search for the shortcut, because I typed it in upper case, so it fails completely.
This is because it’s not smart enough to ignore case, and there’s a bug, since it is being case sensitive, I should be able to enter another shortcut with the opposite case, which is bad, because I would need to create 2 shortcuts for every search that I want to not be case sensitive, but the bug is that if I try this as a work-around, you can’t enter a shortcut in upper case, it converts it to lower when saved. Therefore, it’s case sensitive when entered, forcing it to lower, but then it will NOT work if you typed it in upper.
Please fix this. If you decide to allow upper and lower, there’s also another fix. Instead of having to create multiple duplicate shortcuts, allow multiple delimited shortcuts for one entry.
So, for the shortcut, we could enter Shortcut: “@GO,@go” to search URL:“google.com/s=”.
