thanks again for the feedback, and of course please feel free to not do anything about it 😉 ! - i just know that 99% of people, pasting something into a field like that, from experience with things like Safari, Chrome, etc, into a single line search field, would expect it to be trimmed - especially if there's no other text in the search field at that time
Of course Alfred could implement this as a feature, by putting a checkbox in preferences somewhere that said "Trim leading and trailing characters from input on paste into search field", which you could have disabled by default.
I of course will just implement as suggested above, a custom workflow to trim it before I paste - it was just unexpected is all, and it made me think twice before purchasing the power pack, as that's a very common pattern for me, and is a very common entry point for many I'm sure - copying text, and pasting it into a search box. You of course have backwards compatibility to think of, but may be costing yourself power pack users if they think this common flow is broken. The checkbox in preferences would address both cases, and could be left as "off" if there's an existing Alfred install.
