This is a minor request that could improve the functioning of the Multimaker window.

If you have a lot of projects, when you select some of them and click on a button, it is difficult to distinguish the projects that were previously selected from those that were not, see attached screenshot. Once the Make tasks are launched, it is not easy to ensure that you have not forgotten a project

Completed projects are highlighted with a green frame when their task is finished. Wouldn't it be possible to do something similar for projects waiting in the queue, for example by displaying their name in a different color until their build is launched and/or completed?

I already use groups, I have quite a few. But when you want to make/publish multiple projects located in different groups, in the Multimaker window, the recent projects list is the most suitable IMHO. Otherwise, you will have to go in group A, then select the desired projects and start the make/upload, then go to group B, select the desired projects and start the make/upload, go to group C, and so on.

I have to admit that other look & feels display the selection much more visibly than 'jAlbum Dark'. But basically, what poses a problem is precisely that it is the selection which shows what has been chosen to be queued. If you select ten projects and once the make is launched, you click somewhere in the list of projects, you lose the selection and nothing indicates which projects wait to be made. Sometimes even the selection is erased on its own. This has nothing to do with the look & feel.

I don't understand what you mean by that...

It can be tricky to make specific changes to a look & feel but it is possible. You can also use other look & feels from third parties. See https://jalbum.net/forum/thread.jspa?threadID=56946&start=0&tstart=0

Using other look & feels wiki entry

‘ You can also add custom looks, such as those available from JetBrains.com Having identified a look you like, you need to scroll to the bottom of the page and click on the 'source code' link. Once there click on the 'src/main/resources' link, then look for a '.json' file, like 'gruvbox_light_soft.theme.json'. Download that file. Open jAlbum's configuration directory (SHIF + CMD/Cntrl + C) and ensure there is a 'themes' folder. Add the .json file to the themes folder, quit and restart jAlbum, the theme will now show up in the dropdown menu.’

And of course there is the wiki entry you made, which details that and more.

You can scroll that list though
