Components

Shop easily with your LiveView and OI Shopping List: the LiveView shows one item after the other of your (default) shopping list, click when you put your item in your chart and see the next one.
The application can track separate prices for each store that you use, and features a high level of customization. Font size, sort order, list columns, and list cleanup behavior are all settings controlled by the user. All of these features are brought together in a crisp layout that is customizable through a variety of themes.This application is ad free and does not require the internet permission.

Proposal

I'm as a users of the app has always using this app in my daily and I think there are some feature need in this app to make more easy on manage all list of shopping.
And that feature is,

1.trash feature

2.manage favourite

I have been look that these both feature miss added in the app,and I suggest to implemented sooner.

Mockups / Examples

The feature might be implemented here inside the app.

When users click on the button,it's might look like this.

Benefits

The benefits of that both feature I will mentioned below.All I know the benefits of that both feature is.

1.trash feature

With this feature the users can restore and reuse the Item or list of shopping that they have been deleted on the app,and I think this clearly very useful for them when manage all of shopping list.

2.manage favourite

The benefits of this feature is if the users have list of shopping that they like very much on that stuff,then they can add that list of stuff on favourite feature and it's will make easily when they taking to look on the app.

I think with this both feature will gonna make easier for users when using this app and I hope the developers will added this both feature inside this application.
