Four account workspaces
Switch between separate encrypted Tumblr profiles without mixing their drafts.
Tumblr desktop workspace

A visual desktop publishing workspace for preparing, organizing, scheduling, and posting across as many as four Tumblr accounts.
The useful part
Qu puts text and image drafts, captions, tags, content labels, templates, publishing modes, posting times, the native Tumblr queue, and up to four separate account workspaces on one screen. Accounts connect through Tumblr OAuth, drafts stay local while you work, and every publishing batch requires a final confirmation.
What it does
Switch between separate encrypted Tumblr profiles without mixing their drafts.
Create, duplicate, search, filter, and bulk-tag many posts from one workspace.
Publish now, schedule a specific time, use Qu posting times, or add posts to Tumblr’s native queue.
Queued, drafted, scheduled, and immediate posts always stop for a final batch check.
