   When user has a big dashboard and many native filters added, the filters 
config modal is very laggy and unresponsive.
   We should:
   1. Improve the structure of components that build filters config modal (for 
example `FiltersConfigForm` has over 1200 lines...)
   2. Reduce the number of unnecessary rerenders (with `React.memo`, 
`useCallback`, `useMemo`). To measure and find unnecessary rerenders I 
recommend library `whyDidYouRender`
   3. Measure the performance of filters config modal with Chrome devtools and 
try to optimize anything that stands out.
