Thanks for your feedback! Yes, UI in the free version is not optimal (anymore) – as we focused on developing our pro version for a long time now (this is why we also officiall retired the free version – see here for details: https://www.ads-software.com/support/topic/were-retiring-the-free-version/).
We′d be happy if you give our pro version a try – which is available as free 30 days trial: not only the UI has been optimized, but performance has also been improved significantly. You can download the free 30 days demo of Maps Marker Pro at https://www.mapsmarker.com/install
best,
