Concurrency management - In a group, more than one person simultaneously update the same transaction, both changes should be merged.
Thanks for the suggestion! I can see how this would be useful, though there are some cases where it’s not possible (for example, if two people both change the total cost of a bill).
For now, we do keep a history of all transaction changes in the comments, so if two people try to change an item at the same time, you should be able to see the details of both those attempted changes in the comments. Sorry that we don’t have a more convenient way to handle this yet!
