Thanks for the suggestion. Please add your SubTotal version, operating system and device model, as explained in Please read before posting. The invoice overview and available interactions differ between platforms.
You can already change an invoice’s status without opening it:
- Windows/macOS: right-click the invoice
- Android/iOS: long-press the invoice
Does this cover the status part of your request?
For the expandable invoice preview, could you provide a screenshot or simple mockup showing what information should appear? For example, should it display all line items or only their descriptions, quantities and amounts?
