This app is simple to use and saves my household the time and expense of numerous unnecessary shopping trips. Suggestion: Add a search input field, and enable Listonic to cynamically filter the entire list of items to include only those that include the character string entered into this field. Reason: The way that I prefer to use Listonic is to add, uncheck, and check items, but only to remove items that are non-reusable. So my primary list is quite long, and it's getting harder to scroll though and find items to uncheck. When I use a PC, I can use Ctrl+F, but that's not cross-platform. Please take a hint from another outstanding app called SafeInCloud, which is a password manager. It very effectively uses this filtering method to allow users to almost instantly go to a specific Web account, for example, even though the entire list of accounts may be extremely long.
