New Features for the Transaction History

[LukasKorba]

New features for the transaction history

The new design allows users to filter and search transactions. See the design:

Sent + Received

Straightforward for the filtering, nothing to do for the search. We have all metadata needed.

Memos

Filtering

How to find all transactions that contains a textMemo? We have a memoCount available but that could be any Memo, not necessarily the text one. So when a user opens a detail for filtered transactions, there might be a confusion, no text memo is presented for a user.

Searching

We don't fetch memos for all transactions for efficiency reasons, we rather fetch memo od demand, at the moment a user taps on a transaction and a detail is presented. This is making a challenge for us to search in memos. Ideas how to resolve it efficiently?

Notes

Brand new feature and a user data, nothing that is already available or established. A user can write a short note and save it for the transaction. We need to figure out where to store, how to store and protect it (encryption) in a way that we can easily filter and search.

Bookmarks

Another brand new feature, a user can mark a transaction as a favourite one (bookmark). Nothing to search here but filters are designed to show only bookmarked transactions. We think this data should be part of the Notes data source.

Read/Unread memo's flag

We will need to show an icon on a transaction with the memo as unread transaction. Once this transaction opens a detail, the unread mark should never be present again. That means we need to implement a flag for the transactions. It will very likely be an array of transaction IDs that are considered to be read.
