### Describe the Bug

I have a folder containing 1800 entries and and when I'm opening the folder the Android app becomes really slow!

### Expected Behavior

I want it to be speedy and fluent (as firefox bookmark manager not chromium based ones because those are slow)

Have a large amount of entries in a folder and try opening it in the app.
If you try to have a large amount of entries in the main folder the app even struggles to open.
