Greetings!

I have some ideas, here some of that ideas
1: to be able to add images from the PC to the publications (I already know that Simple Image Upload exists to do it) but it would be much better if it were included with SMF, since it would be better and with more corrections and with a better functioning and effort than Simple Image Upload, the images that are uploaded from the PC to the publication would be stored in an image hosting service such as ImgBB or Imgur.
2: to be able to put icons of social networks in the profiles of the users and to be able to share publications in those social networks and put walls in the profiles: (I also know that there are add-ons to put icons and Breeze for the wall) but, once again, it would be much better if they were included with SMF, Breeze does not work in my forum, and it would be excellent if the SMF team made that wall option, in addition the social network icons of the add-ons always have the old icons of those social networks , better than if they were included in SMF they had the current icons.
3: Add reCaptcha: (And again, I also know that there is a complement for that) but, again, it would be easier for SMF to have it included.
4: Modernize at least a little SMF: SMF although it has a nice classic style (which in my personal opinion I like) needs modernization, it has even a modern style for those who like modern forums, or mix classic features with modern ones, they refresh automatically when a post is published, to be able to put comments infinitely in a publication without dividing it into pages and other modern things that would be mixed with the classic.
Those are my suggestions, here is a small explanation of them, most of my suggestions already exist in add-ons, but if they were included in SMF it would not only be better because the SMF team would create them with effort, dedication, without errors and better than when they were add-ons, but I also think that as soon as you install SMF you should have enough useful functions included, and not that you have to waste your time downloading them from the add-ons page, because it's almost impossible to have a forum here without add-ons Also, since SMF 2.1 is in development, some of these suggestions could be included in this future version.
Bye!
