1. Keep the tags icon shown. Don't hide it when there's already tags on an item. Things changes the work flow when you go through many tasks. At least add the options to keep it shown in settings.
2. Swipe right needs to have more edit features. When you're editing an individual task, there's the "Move, Delete, More" menu down at the bottom. Add all the features of a task to that. As in, add "When", "Tags", "Deadline", "Move", etc - put ALL of them there. Then, when you swipe right to select many task, instead of having the "When, Move, Delete" menu at the bottom, just use the same menu as the individual task menu. This just adds consistency and allows us to edit more tasks quicker. Especially if I have a few tasks with the same deadline, I have to edit each individual task indepently and that takes forever.
3. Bring the keyboard hide button down with the keyboard. Or at least be able to drag it to the four corners of our content. This is really irritating with the plus models since I have to move my hands all over my phone just to put the keyboard away with the button.
4. Create a product key system so people can download the app for free, mess around with the demo project (just disable them to add anything other than what is described by the Project). Then, when they want to officially use the app, existing users can enter in their product key for a discounted upgrade price, and new users can purchase their product key for full price. This will allow people who are unfamiliar with the app to try it out, encourage existing users to stay, and maintain the $10 entry price. Obviously this system will have to keep track of which ipad/iphone/mac version of the app the user has purchased (to ensure the user pays the correct entry price), but that's three easy flags to keep track of.
