Checklist improvements

[vertigo220]

Apparently check lists are already being redone, but I wanted to give my thoughts which can hopefully be considered during that process. I tried over two dozen notepad/checklist apps and only a few even come close to doing them right, and NotallyX is one of only two that is close to it, but it's still lacking a bit.

One of the things it actually does that almost no other app does is allows multilevel/indented list items (a few allow for indentation, but they don't treat the indented items like subitems where checking/unchecking the parent/children affects the other(s)), and it does it in a very easy way. Unfortunately, it only provides for a single sub-level. So the first request is to allow several/infinite (ideally) or at least 3-4 different indentation levels.

Another feature it's missing (and again, in fairness, no other app I've found has this) is the ability to collapse/expand the list levels. This would be useful for example for a grocery list, where it can be structured by categories which can be expanded as needed and collapsed to make it easier to navigate the list.

The third feature I'd like is the ability to add notes to list items. This was mentioned in another issue and would be extremely useful. I'd much prefer being able to have separate notes attached to the lines/items than just tacking them onto the end, which can get messy. For example, I like to note the price of various products at various stores, and this, combined with other notes, would really clutter the list. Doing something like having a note icon at the end of each line that can be tapped to open a popup or expand a line underneath to add/edit/view notes for the item would be very handy. This icon could change to reflect when there's a note and when there isn't. It wouldn't necessarily have to be a separate field, either, but could simply be a button to show/hide a line or group of lines below the line the icon is on.

Add images (or probably any attachment type) inline instead of at the top. Again, using a grocery list as an example, this would be helpful for having a picture of the item along with it on the list, to make it clear what to get, or to be able to attach info to the items, e.g. a picture of the item's nutrition facts and/or ingredients. And the pictures wouldn't need to actually be in the list. There could just be an icon/link, similar to and maybe next to the note icon, that would indicate the list item has one or more pictures/attachments, and tapping it would show them, but only the ones for that item. So they could just be stored separately and linked to. Also, it would probably be advantageous to be able to take a picture directly when choosing an attachment type vs having to take a picture then select the picture, but I can understand it might be preferred to avoid camera permissions. Though with that, it would also allow things like scanning barcodes and inserting them in the notes as well. Not really sure how useful that would be without the app also having the ability to do things like performing a web search on the barcode, which would be cool and potentially useful, but may also be outside its scope. Just tossing ideas around.

Finally, a toggle to show all items vs unchecked ones, to allow for easily checking to see what's left on the list that needs to be picked up. And perhaps a counter of x/y items where x is checked or unchecked and y is the total, as discussed in #115, but visible within the list whereas that discussion seems to be focused on the main screen.
