Ok thank you …
although … if i may …
As i can see, changes from sp 4.x to sp.5 are deeply impacting the former methods of how to exploit sp.
As far as I explore the new way of managing attachements in post, I notice that many of the former existing functionalities
– changed (e. the way some functionalities became new plugins …),
– or sometimes, disapeared (e. possibility to manage attachements via tinymce media/image buttons ; possibility to manage uploaded files and make them available to several post ; possibility to add new attachement when re-editing a post … ),
I can not contest that may be the sp code has been “enhanced”, but in terms of exploitation and productivity for the user i am, it is really a regression : all former habits, experiences and “users skills”, gained through a long and hard training, look like obsolete 🙁
I’m getting afraid of the new coming releases as far as my personal and professional development is not to become a simple press expert.
I’m really sorry for that comment, as it is obvious you are experts, capable and efficients. But after a long day of a tough work to understand that the way we used this forum doesn’t exist any more … is hard for me.
Sorry again 
Stéphane
