Must have!
No funciona ni siquiera me aparece en el menú del ordenador, tampoco me aparece la opción de eliminar el programa...malisimooo, para que colocan algo que no funciona perdida de tiempo ._.
Makes working with GTM easier. Like it a lot.
Un indispensable pour une utilisation un minimum avancée de l'outil GTM avec en bonus le plein écran. Merci !
L'éditeur de code intégré au TMS est un gros oubli de GTM - du coup add-on très pratique pour tout faire depuis l'interface avec en prime une vue plein écran. Un must have en attendant que Google corrige ça !
This is such a great tool, no more copy paste issues!
