UI need some fixes

Hello, I’ve a suggestion for the Niotron UI. In the list of components, the vertical scroll button is very small and prevents us from moving by move from top to bottom freely, our finger is much big and as a lecming 90% of the time, or we press outside the list or insert a component by error. It isn’t possible to move by dragging within the list, at the time we touch it, what we’re inserted even if we are moving. Please, if you can, make that scroll button bigger.
