It would be good to have Qlik Sense Desktop available for installation on Windows Server rather than just locked to WIndows 7/8/10. With the growth of SaaS and the introduction of Qlik DataTransfer, it would make sense to allow Desktop to be installed alongside DataTransfer to facilitate more complicated extract and load procedures from on-prem data sources i.e. incremental loads.
Desktop could be turned into a Client-Managed 'lite', and bundled in with SaaS, but removing the development of Sheets etc. just loading data.
