ToDo X

ToDo X is a native Cocoa to-do list application for OS X. Its user interface is deliberately, almost ruthlessly simplified, yet it provides plenty of power under the hood: it allows you to maintain multiple, prioritized lists of to-do items, each with unlimited attached notes and clickable links to Web locations, documents, folders and addressbook entries; you can link items to multiple lists and use drag & drop to copy, link or move items between lists; you can search, display or print the union of selected lists. You have instant access to your to-do lists from the dock or the menu bar, and you can create a to-do item from selected text in any application that supports the Services menu. ToDo X can import from many different file formats including .ics calendar files and plain text files.

• A Split command has been implemented to split the notes of a selected category or to-do item into pieces, creating a new to-do item from each piece. This is useful if you've been keeping a list inside the notes, and decide that you want to promote that list into actual to-do items. (The original notes are unaffected, so experiment with confidence.)
• There are now three window styles available, chosen from a new Window/Style menu. This obsoletes the "Hide buttons & headings" option, which has been eliminated.
• Hiding the headings no longer suppresses the (momentary) display of the number of categories and to-do items.
• Command-up-arrow or Command-down-arrow will jump to the preceding or following selected row in the currently active list. This is useful for browsing the to-do items selected by a search.
• Command-return or command-enter will open the most recently selected row in the currently active list for editing, without perturbing the selection. This is useful in conjunction with Command-up-arrow and Command-down-arrow.
• Command-double-clicking a selected category or to-do item will likewise open it for editing without perturbing the selection.
• It remains the case that when the option key is down, techniques that normally open a category or to-do item for editing will instead launch any links contained in its name or notes.
• In the Preferences and Print panels you can now check or uncheck an entire set of checkboxes by option-clicking on any one of them.
• Improvements have been made in the dragging and pasting of iTunes items, email addresses (from Mail) and contact groups (from AddressBook or Contacts) into the Things To Do list or the notes in a New/Edit window.
• Dragging a folder into the notes will no longer incur an alert asking if you really want to do that.
• User interface sounds are now played more responsively, and (except in OS X 10.4) will follow the Alert volume and "Play user interface sound effects" settings in System Preferences.
• Button artwork has changed to avoid a visual calamity in OS X 10.10 (Yosemite). It is now invariant across releases.
• The default font for lists and notes is now explicitly Lucida Grande, for the same reason.
• The menu bar status item tries to restrict itself to colors that will remain visible against a light or dark menu bar.
• All menu items now use the ellipsis character in place of dot-dot-dot.
• The replacement string in the Rename panel now defaults to "$0".
• The application Help pages have been updated to HTML 4.01 Strict.
• The app has been signed to make GateKeeper happy.
