Simplified version with direct mp3 import/export

Dear moderators! Hello! While working with tracks In many cases it’s needed only to cut silence in the start and in the end. Other actions aren’t needed. In such situation a simplified version of audacity would be better. The meaning is, that I ask to develop the simplified version, that would support minimum of effects, except “cut from start”, “cut to end”, “Remove DC offset”, but in return support…direct mp3 , rather than aup, import/export. As a result, sound would have less distortion after import/export. I know, there’s a program “mp3directcut”, but it’s, to my mind, uncomfortable at work. Thank you!
