Daily you can see the following kind of article: “7 simple ways to lose weight,” “10 things to make you happier,” etc. The problem is that, by the time you finish reading through the list you might remember a couple of the items from the ones listed in the article. Implementing them is even more unlikely because it’s hard to do so many.
A place where only “one” articles are published. Instead of “7 habits to …”, the article should be about “One simple habit to …”
Checklists are very beneficial to making sure you do not forget routine but important things. Their usability diminishes as time goes on because you start checking them out without thinking because you “already know” from constant repetition.
Use checklists that dynamically change both the order of items (where applicable), and the phrasing of each item. This way you will have to pay more attention even after doing the same checklist many times. The more combinations there are for the checklist (and this can be expanded over time, even having some often used old versions removed for a time), the less the chance for automated and risky checklist fulfillment.
Many times you get links that are for a particular device (mobile, desktop) because the sender used that device when sending them to you. When you click on these links, however, you might be on a different device and will get unreliable results like blank or poorly formatted pages.
Have the client software you use, detect these discrepancies and automatically correct them, at least for all the main link sources like Amazon, etc.
You can undo most of what you did yo something you draw or paint with a digital device so experimenting with new creating ideas on work you are doing has no cost because you can always go back to a previous version. It might be fun to have a similar option when you are drawing in the real analog world and not on a digital device.
A transparent “paper” that behaves like real paper, so it reacts to your drawing and painting utensils (pencils, pastels, etc.) in a similar way to real paper. You can then have new layers of this “paper” added to your work and experiment. If you don’t like the result, just through away the top layer(s) of this “paper.”
You have patterns you repeat when answering emails and otherwise messaging. These are similar to other peoples but have your style of expression. Today you can already automate these on many devices by using snippets and a shortcut. The only problem is that they are always exact copies, so answering the same person twice will reveal this fact.
A smart snippet software that, while you are typing, analyzes your words and suggests an auto-completion of the whole sentence and not just one word. It will do so with a slightly different variation based on how you started your sentence and your writing style. As you continue writing what it suggests changes until at some point, you choose to use it and complete the sentence or even a whole paragraph.
