Here's my opinion on how this forum should improve and which features it should add.
1) Editing and deleting
The top comment is the original one and the bottom one is the edited version.
It should be an editing and deleting option for opinions, MyTakes and replies. Sometimes users can have typos they wants to correct, they clicked the "send it" button with an accident or replied to the wrong person. In such cases it would be practical with features like that. When you're editing a comment the edited version should show, but it should be a feature where if you're clicking into a little icon either over or below the comment, you should be able to see the editing history where you can see the original comment and all the other edited versions if the user have edited it multiple of times.
When an user deletes a comment regular users shouldn't be able to see it, but moderators can see it so the person don't get away if it's a troll comment.
2) Don't exit after submitting an opinion
After submitting an opinion pressing the "Send it!" button the site exits automatically.
After an user has deleted his/her opinion the forum is exiting the question page and is going to the live feed. I thinks it's annoying when it happens and if I wants to stay longer at the side if I for example wants to reply to an opinion. Therefor I thinks it would be better if the forum don't exit the page and that the users can rather go to a new page by themselves.
3) Getting rid of trolls or getting a own troll section
A own section for trolling and jokers.
I thinks the site should be better at removing non-serious and troll comments. Some people wants a serious discussion or a serious answer. It gets a bit annoying if many users are non-serious, trolls or writes too short answers that's not answering the question at all. The site should try to get more trolls removed. They could also add a troll section where trolls can have it fun and if they're posting troll comments outside of the section they would be banned.
4) Volunteers fix people's grammar
Some comments is very difficult to read and not everybody have English as their first language, so for them it can be extra hard to understand. So I thinks some people should be allowed to be "Grammar editors" who are volunteers who's allowed to edit comments. But not everybody should be allowed to be editors like how not everybody is moderators. I thinks if this forum is adding this feature people should be able to see the original comment too so they can compare the original and edited one. Most people writes understandable English, but not everyone does. Some writes "Hi, m8. U don't like pie. Me n8ther" ,and it's comments like that the editors should be allowed to edit.
5) Select all button
An invite all button.
When you're inviting friends on this site you've to invite them manually. It would be easier if you could have a "Select all" button where you could invite everyone much quicker instead of inviting one person at a time.
I thinks the site also should add a date feature where users can see which date an opinion, MyTake, question etc. were posted, so people don't need to wondering when it was posted and to know if the post is outdated or not.
7) Block anonymously users
Now you can only block people who isn't anonymously. But sometimes some anonymous people spams people's questions and it's not always possible to report them because of their comments is just annoying, but not severe enough. In such cases being able to block them would be practical.
8 ) Add new history category
I thinks this site should add a history category so history interested people can discuss history. Some of my questions I've asked would fit that category much better than the other ones and I thinks others would also like to have one. I've asked questions about both hygiene, clothing and art from the past.
9) The amount of characteristics
The opinion field should be expanded so people who wants to wright longer opinions can do that. Sometimes people wrights rest of their comment as replies instead of as a whole opinion because of limited of space. On GAG the limit is 2500 characteristics, but I thinks it should be 4500 instead or more.
10) GAG don't need to choose MHO
Sometimes it's not suitable to choose MHO. Either because none of the answers answered the question and sometimes all the answers are equal helpful. Example in questions where the asker asks which color are your favorite one there is no questions that's more helpful than the other ones. So I thinks the askers should be allowed to choose one by themselves without GAG forcing to do so. They should at least have an option where the user can choose if GAG should be allowed to choose MHO or not at least. Sometimes I'm too busy and lazy to choose MHO without being against GAG choosing it for me, but other times I don't want them to choose it for me.
