There are several usability issues with the "Git-LFS not supported" notification in the UI (where it also informs of new versions of SourceTree):

• There's no option to dismiss it - I don't need Git-LFS support, so it not being supported is intentional, yet the notification is permanent. (Technically it can be dismissed, but it comes back after app restart.)
• The subtext indicates that I need to update the version of Git I'm using, when in fact I'm using a version that does support Git-LFS but have opted not to install that component, which is an install time option on Git for Windows.
