Impossible to mark many replies as a solution

What is your operating system?
kalmer@kalmer-GL752VW:~/Linux_Pentablet_V1.2.14.1$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

Release: 20.10

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
21.01.29
No.

Can you repeat the problem? If so, what are the steps?
1 Find a post that has many replies that offer a solution!
2 Try to mark all of them as a solution!
3 See that once you mark another reply as a solution the former will be unmarked!

It looks like you posted in the wrong category. By mistake.
The Bug category is for Shotcut related bugs, not problems with the forum.

You need to report the problem related to the forum on https://www.discourse.org/, That is the site you could post forum related problems.

I don’t see they deal with issues as that part is totally missing in GitHub.

To be sure, it’s not a question specific to SC. Every software has its limitations and user wish-list items, and that’s the case here.

This is not an issue or bug but rather an opinion, and I disagree with it. I am fairly certain it works this way by design. If you want to show support for other replies use the like/heart icon.

You can find many threads on the forum software related to the solved feature if you want to find something related or discuss further.
