Menu tabs is one of the most important functions in SC
one way , is to tune app navigation. if your grid opens a form app in a tab , you can set up close after update in the form navigation settings. this will actually close the menu tab for your form after updating.
(the same for inserting). this kind of work around back button.
there is also a setting in your menu, to generate context menu for the tabs. this allows to close several sc menu tabs at the same time.
menu tabs should be supported. also from sc_redir macro.
also the current tab is unpredictable, it jumps to whatever but not the last tab when you close a tab.
also in SC dev itself. after app generate, you close the generate tab but end up in another app.
several times i trapped in, cause you start developing not what you just generated. take care!
