Tublme

Tublme is a beautiful and powerful, yet easy-to-use, Tumblr desktop client. It makes browsing Tumblr a whole new experience with its minimalistic approach.

Features:

• Lists - As in Twitter, a list is a selected group of users. Just add people (you don't even need to be following them) to a new or existing list and you'll be able to check the list timeline whenever you want.
• Saved searches - Apart from keeping a history of your recent searches, Tublme me lets you save the ones you want.
• Keyboard shortcuts - So you prefer using the keyboard? No problem: browse the Dashboard, make a search or like a post using simple keyboard shortcuts.
• Multiple accounts - You can add as many Tumblr accounts as you want and change from one to another instantly.
• Simultaneous uploads - Are you uploading a very heavy post and, meanwhile, you have finished writing a new one? No need to wait. Publish it and Tublme will take care of it all.
• Work offline - Did your Internet connection failed? Was there an error while uploading? Did you have to cancel your upload? Tublme saves your post automatically for you to try again later.
• Notification center - When publishing a post, when you have new followers, etc. And if you prefer using Growl, no problem, Tublme is compatible.
• Retina ready - Tublme is optimized for the new MacBook Pro Retina Display.

• Beautiful interface
• Icon in the dock, in the menubar, or both
• Markdown, HTML, and RTE support
• QuickLook support when viewing posts (Space bar key)
• Lots of kitties...
