make the download link for "you need dokan.dll" clickable
When I choose "Mount this changeset in Plastic Drive", I get a long and confusing text message because I do not yet have dokan.dll installed. The text message contains a long URL with the download location.
Even if you are not going to make the installation process automatic, you could still reduce friction by making the download URL clickable. This makes the URL stand out from the rest of the text, and makes 'the right choice' easier.
You're right, we should handle this better. The dialog is copyable (just CTRL-C) but this is no excuse.
We just implemented a quick solution, didn't spend time on a custom dialog, just used an standard one.
About automatically distributing it: yes, would be nice, but since it is free, we prefer the user to download it.
