- Previously, effects could be changed into types that take different amount of inputs, e.g. from "add" to "glow", which led to undefined and glitchy behavior (unreported bug). Fix by requiring same input count for new effect. - Previously, strip names were not updated when changing effect type, which tended to be confusing. Now, if the default name was not changed, update to the new effect type name. - Remove "effect strip" menu from color and text strips. Although they are effects internally, to a user, this is not clear, and providing the option to modify effect inputs in these cases doesn't really make sense.
