The interface was intuitive to use, very easy for my users who are not developers at all! It helped us get our application up & running quickly with little hassle from development side (especially given there's no backend!).
There were some features that I would have liked which weren't available out-of box or required configuration - we needed custom integration workarounds where necessary because they didn’t support certain data sources by default like CSV files etc., so had limited customization options as well while keeping it extensible enough if need be later downthe line too.. We had wanted an SPA version initially when starting off this project; however due API changes made during early stages meant having 2 apps instead one being both frontend + api server endpoints worked best approach here :) No dislikes though really!! Excellent product overall especially considering its ease / simplicity to setup alongwith low technical requirements involved once you do understand how things.
