Expert mode don't need to do verifications after each file switch

[asmorodskyi]

Currently selecting new file take some time because after each change there is some validation running . This makes editing session really time consuming and not pleasant . But ofc I clearly see reasons why we need this . To keep CAP repo in workable state but give user more comfortable environment :

• on file modification of any file not directly save changes but create some temp modified copy/patch
• after user did all needed changes he/she suppose to press some kinda of "Submit" button which will do validation and will apply changes in case all valid
• during one "modification session" user may switch between files faster because we not doing any checks
