Making tracks with the Jokosher audio editor
Beyond the basics, Jokosher is extensible . It has a plugin structure that you can set up by clicking on Extensions | Manage Extensions to add, remove, or enable extensions for use. If the plugin is configurable, the Settings button is enabled.
More extensions are presented on the developer page of the project website  and in the Jokosher user forum . Of these, I really enjoyed the "Freesound search" plugin (Figure 6), which helps users choose from an impressive selection of freely usable samples from the Freesound database (see the "Freesound" box).
Freesound  is a database in which users have put a huge collection of samples, sounds, and noises that are freely usable, in contrast to commercial sound libraries. The samples are licensed under the Creative Commons Sampling Plus license, which allows their use for commercial and non-commercial purposes .
Despite some very good approaches and solutions in Jokosher, some criticism remains. The lack of a vertical zoom function turned out to be highly impractical. Although you can change the width of a track in the main window, the height remains unchanged. In the mixer view you can't scale tracks in either vertical or horizontal direction, and this keeps users running back to the main view to edit work.
It is impractical and downright annoying that you cannot select multiple track takes to move them at the same time. To add a sound or an edit at the start of a composition you have created, you are forced to move each track separately.
For a deeper look at Jokosher, check out the program documentation . Despite its current weaknesses, Jokosher seems quite advanced. The program shows huge potential for becoming a serious alternative to more established programs such as Audacity.
All told, Jokosher is a powerful audio editor for budding musicians and audio amateurs. The intuitive controls and attractive design make Jokosher a good option for smaller projects that don't require a lot of editing.

We're working on it.As you mentioned, Jokosher is a work in progress. However I think you did a really good job at covering the things it does well currently. There were few criticisms in the article. I guess this means we are doing pretty good
I'm sure there are many things that could be a lot better, like the one below. You can always let us know.
"It is impractical and downright annoying that you cannot select multiple track takes to move them at the same time."
I found there is already a bug for this one, but I will make sure it is top priority for next release.
