Visualization of Large Amount of Spectra in Virtual Observatory Environment

This paper presents overview of new features so far prepared for new version of spectral analysis tool SPLAT-VO that allows to retrieve a large amount of spectra (and other data) based on its characteristics by detailed querying a virtual observatory's resources. The overview is focused on enhancements of user experience, work with simple application messaging protocol (SAMP) and other interoperability that improves work with global list of spectra, plot window and analysis menu.
