I just posted another update to TodoPaper. Included in this update is:

• Added a Search History function
• Added the ability for the document outline pane to remember its size
• Added a short-cut to toggle the document outline (Alt+O)
• Added new date tag format presets
• Revamped the find and replace dialog

One thing to notice is the Search History function. You can now save your searches by pressing enter in the search textbox. You can see your saved searches by clicking the magnifying glass icon in the textbox.

I will continue to work on implementing some of your suggestions. I really appreciate your comments and hope to continue making TodoPaper a great application. Thanks again for all of your support!
