A simple application to illustrate that problem, could be an application which displays all images within a folder in a list view. Take a folder that is packed with a...

I think images on the web is overkill, loading images from disk is enough, you can add a sleep(1s) to simulate slow disk I/O.

I've mitigated it using a bunch of LRU caches and: ```rust fn row_data(&self, row: usize) -> Option { let result = self.fetch_row_data(row); if TITAN.library_results_enable_prefetch { for i in 0..TITAN.library_results_prefetch_size {...

This is understood, but when I compile my rust code, this could generate the slint compile commands. So I need to build the app once, then the slint preview will...
