If you enter a lot of entries during the day like myself, it is easy to loose focus on those items, tag them correctly, give them a location or put them in the right group.

For this task, I created a SmartList called "Check". It basically shows all items that still need processing. First, think of which items in a 'todo' you require to be filled in. In my case that is:

- List (not being the Inbox)
- Location (so I know where I need to execute this action)
- Tag (so it will show in in the right smartlists and search actions).

Then, create a search. In my case:

isLocated:false OR isTagged:false OR list:Inbox

Save this search as a smartlist. I called it "Check".

If I go into this smartlist, I immediately see which items need processing. As soon as I have processed them, they disappear.

For extra 'awareness', you can add this Smartlist to other smartlists, so the items are even more visible of processing. Just add a 'OR list:Check' to your filter and the non-processed items will show up.

Hope this tip helps you remember the tags!
