The Waveform Editor allows you to make super quick convenient edits (like trimming, normalizing etc) directly in the editor without needing to open up external audio editing software like Audacity. Having this in UEFN would be a big QOL improvement especially for those using SFX found online, as they often come with dead air at the beginning or end of the file that needs to be removed. Please consider adding this functionality inside of UEFN! Thanks
