The visual representation of your docker containers can be very useful to manage them, so you dont have problems with some commands that are not working as expected or because it wasnt clear enough for me what I should do next in this case. You need good knowledge about linux command line before using mina! Its easy-to use but if youre coming from windows world its hard at first time when things get confusing since we know how everything works there :) There's no way yet (as far i understand) which allows us managing our images directly like gitlab does. If someone wants an alternative for github/gitlab he has two choices - either they build their own image repository management system by themselves OR continue searching other alternatives such as BitBucket etc...
