feat: add pagination on the Receive page (optional)#4501
Conversation
Previously, opening a wallet with many subaddresses would cause severe lag and impact usability. This change introduces pagination to the subaddresses in the Receive tab.
To reproduce the issue, create a wallet with many addresses in monero-wallet-cli. For example, using:
```
address mnew 1000
```
30+ times in monero-wallet-cli will create a wallet with 30,001 addresses (like a very active BTCPay wallet). Without this feature, the app will lag on a performant PC. With this feature, it shows a "Loading addresses..." message while loading the first "page" of addresses. As a Quality of Life (QoL) feature, a "Scroll to bottom" button allows loading all remaining addresses at once.
- Add pagination support to the Subaddress backend.
- Add "Enable subaddress pagination" setting to Interface section.
- When pagination is disabled (default): behaves exactly like original GUI.
- When pagination is enabled:
- Load first 100 subaddresses initially.
- "Scroll to bottom" button loads all remaining addresses.
- Loading footer shows progress during fetch operations.
Is it possible to make this dynamic? Because on a smaller screen you now have two different ways to scroll, basically I would have to scroll both on the outer and inner layer to the bottom.

Yes, I noticed that but accepted it. It's definitely possible to make it dynamic to try and fit the window size to try to only get one scrollable section I wonder how or if to try to resize that dynamically as the window is resized, though. I'd appreciate any more details / specificity you can provide if you'd be so kind as to expound upon what you'd like to see |

Reg "dynamic" - i am no QT dev, but i also attempted through blood sweat and tears to add some kind of dynamic resizing and failed. #3868 is related as this would also benefit from that. |
