Eitot: It would be nice if you were able to edit your posts for a few minutes without adding the ‘Post edited [date] by [user]’ label. Sometimes I like adding a few small things right after I posted something, but it just looks a bit… stupid if everyone sees that I’ve edited it. Just one or two minutes, that’s all I need.
Another suggestions would be to get rid of the popup to write your posts. This is such an usual practice and I don’t really like it. If you have multiple tabs opened, it can become rather confusing. Just keep everything on the same page. :-]
Installing
Barefoot Essentials 2.0 will solve both of your issues for now :)
"Author's Description
Barefoot Essentials for GOG.com is a userscript designed to significantly enhances the GOG.com website. Here are some of the features and enhancements this script provides:
Site-wide
The navigation bar at the top of the website can be made to fade or slide away while you're not using it
The drop-down menu on the navigation bar is now instant
Links are added to the drop-down menu to allow you to go directly to your shelf, game list, wishlist or gifts
Notifications for game updates, private messages and/or forum replies can be suppressed, so that you see only the notifications you're interested in seeing
Forums
By popular demand, forum topics that appear to be giveaways can be grouped and listed separately from other topics
Forum topics
"Quick post" and "quick reply" make it easier write posts
Adds support for spoiler tags
