Beta Releases / MC V17 Early Access PREVIEW 5
Last post by Mathias (Author) - Today at 15:18:10Preview #4
----------------------------
Version 17 is not ready for stable release anytime soon, But it already has a lot of new things that need testing
Not everything added to v17 might be included in the final release.
v17 contain many MAJOR rewrites and new addition.
This is a early preview. Since it is a early preview it is time locked. and will stop to work after sep-30. (but a new updated version will be out.. )
However it will not be possible to auto update this version until in reached beta. there might be more 16.x releases with fixes before this is officially out
Since this is early preview. NOW is the time to come with feedback you want something to change. How a features with file tags or folder specific settings works or something like that.
Since this preview is developed separately from v16.x, When a new preview is released, it might not have all the fixes or addition that 16.x has. Right not V17 Preview has everything 16.2 build 3205 has. (I think)

Last post by elmo7sharp9 - October 26, 2026, 13:23:06AI suggested 5 ways to NOT get this to work, before I had to cut it loose... 
A key binding in the application would be ideal,
exposing the parameter to scripting would be my 2nd choice.
Thanks for your reply and for the magical application itself, which I use for 95% of my file operations...

Last post by Mathias (Author) - October 26, 2026, 10:33:15I can't reproduce that.
If you can provide step by step on what you do and what goes wrong, I might be able to check it

Announcements and News / Re: Forum System Updated
Last post by total_annihilation00 - October 26, 2026, 07:27:38Could you add a built-in dark mode theme? My custom CSS user style isn't rendering some elements correctly in dark mode. A native dark theme would be helpful. I didn't encounter this issue in the previous version.
P.S. Never mind—I've updated my custom user script, and SMF topic titles now display using the custom theme's colors.

Last post by total_annihilation00 - October 25, 2026, 15:45:13I noticed two issues with custom icons:
Could you clarify whether this is by design or a bug?
- Custom file icons (Configuration → File Type Setup) appear in Details View but not in Thumbnail View. Is this a known issue or expected behavior?
- Custom folder icons appear very small in Thumbnail View—the icon doesn't scale to fill the thumbnail area, so only a small portion is visible.
