Thx for the kind offer. There's a list view where I select one or many video/image cards, and edit their titles, tags, descriptions in a single edit box singly or multiple. It's not about media editing, just their titles, tags and dozens of other data. Redux store contains all 200 image information as well as undo history. Here's the issue - when I put there 200 things to edit, the screen becomes very slow to use. Like the mere act of selecting and having its title/description etc appear on an edit box is 2 seconds. I have installed redux and react dev tools out of curiosity to understand what's happening. My conclusion, is that over 200 images to submit in batch combined with the undoable complex data store can't be handled. So I went to examine redux website and source code - which appears quite thin and performant. At the end I think react gets slow to update 200 cards from the complex store after redux store gets updated. I currently don't have some things to submit otherwise I would post some animated screenshots. But next time I have I can post a github issue and pls let me know what kind of data I must include from to react dev tools for performance check.
