My usual workflow with archive files (that I've just downloaded) is clicking the file in my browser's download list to open it and then extracting it. In WinRAR, the extraction path is pre-filled to be "<archive directory>/<archive name>", and there is an option to automatically open this folder after extraction. 7-Zip doesn't have this, so I'd need to manually add the archive name to the extraction path and then separately browse to it. Granted, if you browse to the archive and right click it, 7-Zip does have an option to extract to an "<archive name>" folder (though this still doesn't automatically open it afterwards), but that's an unnecessary extra step.
There might be an oversaturation of Mac native apps on the HN front page relative to Linux/Windows native apps. I, too, feel a bit disappointed when they are posted for the same reason as SomeCallMeTim (especially if it's not clear from the post's title that it's Mac exclusive and it only becomes apparent deep into the linked page), but I also know there are tons of native tools for Windows and Linux — they're just not discussed here as often. Though this could also be confirmation bias on my part.
Would you be able to give a ballpark figure for the extended licenses? I'd rather not get into a sales funnel before knowing what kind of numbers I should expect. In particular, I'm interested in being able to use the full set of icons rather than being limited to 100/project (and having to track that).
