If a user is listed as a co-author on a project, that project should appear in their profile under the "Projects" tab.
Bug: in the admin panel, it's impossible to select a badge to award for publishing a project without linking it to a tag — the dropdown list has no options. The same function works fine in the tag add/edit menu.
Minor bug: in one of the previous versions, a pop-up would appear if you uploaded a cover image larger than the maximum allowed size. Now, there's no pop-up at all. The restriction itself works — the image doesn't upload — but there's no feedback for the user.
Following on from the previous point: the project creation window should include information about the maximum image size allowed for the cover image.
If possible: in the project creation window, I'd like to see formatting tools in the "Details" field, similar to those available when creating a forum post. If that's difficult to implement, then at the very least there should be a note indicating that formatting is supported in this field.
When clicking "Feature on profile," there's a one-second delay. It would be nice to fix this, similar to how the like button was fixed.
In the project creation window, there are some visual issues in the links section:
- The "Links" heading differs from the other headings in the window
- The overall spacing of elements needs adjustment
- The "Custom label (optional)" text slightly overflows the input field
Attaching a screenshot:

In the list of project authors and co-authors, a comma is used as a separator, but it doesn't look very neat. In my opinion, the comma should either be raised to align with the author names (rather than with the avatars, as it is now), or a different separator should be used. This applies to both the project card and the project page.

- + The hover effect on the name of an author who is not a forum user should be removed.
In the project creation window, when you select a tag and the parameter list appears, required parameters have an asterisk "*" — it's colored white and blends into the background. Logically, this asterisk should be either red or match the heading color.
- + The same kind of asterisk could be placed next to the "Title" heading at the very top of the window, since that field is also required.
Visual bug: if the text inside a button is long enough, it doesn't fit within the button. This is due to the CSS property max-width: 150px;. Also, word wrapping should be added so the button doesn't end up overlapping the like button.

If you scroll down the projects page, open a project, and then go back — the entire projects page reloads from scratch. It would be better if the previous scroll position was remembered in such cases.
In the admin panel, there should be an option to reorder tags, parameters, and buttons, and this order should also affect how they're displayed on the project card/page and elsewhere.
All dropdown lists should be styled to match Flarum's visual style (except, perhaps, for the admin panel).
In the project creation window, at the very bottom, in the "Linked discussion" section, I think it would be better to add a discussion via a link rather than by its ID.
On the project card, there should be a small visual gap between the parameter name and its value.
