+* Add ability to move subsheets in the subsheet tree.
+* Add Flip X and Flip Y functionality to TileSheet Editor.
+* Add rotate functionality to TileSheet Editor.
+* Add draw line tool to TileSheet editor
+* Replace file picker combo boxes with a browse button and file picker, and
+  support for dragging files from the project explorer.
+* Add ability to jump to a color in a Palette by double clicking on the
+  color from the TileSheet editor
+* Add ability to create directories.
+* Add ability to add files to specific directories.
+* Add ability to delete files from the project explorer.
+* Ctrl-<num key> keyboard shortcuts for jumping between tabs.
+* Fix Palette Editor to ignore keyboard input when popups are open.
+* Palette Editor move color mechanism now uses drag and drop.
+* Add ability to reorder Palette pages.
+* Add warning for closing a tab with unsaved changes.
+* Add ability to close a tab with Ctrl/Cmd-W
