Some more updates and fixes.

A bug fix for the chase effect.

Two new features. 

One to give a choice on importing Audacity marks to Bars(original) or beats. 

Second, fix the way the editor showed the multiple parallel intents that are generated by pulses, Mainly for discrete items that use multiple colors at the same time in the effect. This one has been bugging me for a while. Helped discover the chase bug that was also fixed in this pull.
