If I just type the name of the package, ie. `'azure'` without the quotes, then the install button stays disabled. If I add a space after azure ie. `'azure '` then it becomes enabled and I can successfully install the package.
Note that my catalog is empty, I don't know if it works better when it's not empty.
Comments: Ah, yes: I should put in a check to require the selection only when the catalog is non-empty. (The reason it works with the space is it assumes you want to execute a "raw" install command with extra arguments - package names can't contain spaces hence I just check for the first instance of a space to switch to this mode.)
