Hello,
I purchased a CS3+ (60216) in 2021, it is software Version 2.3.1 (8).
I run up to 5 trains on my layout simultaneously.
But I do not use the CS3+ to control any solenoid or on/off accessories.
It works well.

My problem:
Currently I have 3 pages of locomotives showing on the locomotive choices screen.
I find it painful searching throught 3 pages of tiny loco icons to find the loco which I want to stop (or adjust speed etc).

Is there a method of showing on a single page only the locomotives currently operating on the layout?
Or perhaps it might show the last (say 6-10) locos used.
Or perhaps it might sort the icons to give preference in chronological order (on the first page) to the last locos used.

Secondly:
I have never updated my CS3+ and purchased a USB stick to do that.
While the system works perfectly now, I am loath to try an update, in case it changes somethng of which I am not aware.
But I can see the advantages in having MFX locos use the correct icon when registering.
Are there any pitfalls in the update process?

Thank you in advance
Kimball

The latest update, 2.5.2 I believe should be problem free. After installing it it will re-register or update all your individual mfx locomotives one by one.
I don't find the icons for the locomotives to be that small (wearing glasses for my old eyes). Page 31 of this pdf CS3 manual shows how you can filter and sort your collection of engines. Also notice that the locomotive page can be dragged up to view 18 icons in one screen.

Bart, above, also mentions this.

Hello
You could also easily change the group on the locomotives you are using to e.g., MISC. and only show that group. (locomotive settings and the info page)
And eg, arrange your CS3 like this:


And in addition, if you have an old laptop or tablet etc, you could use it as a supplement using the web browser.
and you can have several windows with different sorting etc.:


It's also recommended to update your CS3 as there have been some big improvements and fixes. And the sorting function has also been improved
The current version is quite stable.
Here is a changelog:http://hovland.net/filer/Maerklin_CS3_Changelog.pdf
Note, it's also expected to be a new major update sometime around April. But it might be delayed.......

The description from Märklin is not the best, but just change it like this:

yes, I would also like to at least have the option to have some extra custom groups.

But I use the groups actively, and also normally add Prussian, Württ and NSB etc as prefixes on the steam locomotive names, in order to get a better sorting on the steam locomotive list.
