Hi @BurningTreeC ,
i worked a little on the sketch for the column-manager I would like to have.
columnmanager.json (1.4 KB)
Unfortunately in my wiki, the flex-plugin is causing some issues.
Mainly tiddlers clicked in the sidebar do not open but trigger an element does not exist error. I guess this is due to heavy modding. Layouts —
The error I get is TypeError: widget.list is undefined
This is now on CPL BTC/TiddlyFlex, you can easily update when @BurningTreeC release on Github.
I add some translation and description, hope you don’t mind. (Ultil feat: t macro and docs by linonetwo · Pull Request #7821 · Jermolene/TiddlyWiki5 · GitHub)
This GH issue may be interesting for you

@BurningTreeC, for hackability or just for changing palettes, it would be great if the icon could use the
tc-image-button classes and styles of the other icons for example to be used as captions in tabs…
for $:/plugins/BTC/TiddlyFlex/icons/layout
<svg width="1rem" class=" tc-image-button" viewBox="0 0 24 24" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><rect width="7" height="9" x="3" y="3" rx="1"/><rect width="7" height="5" x="14" y="3" rx="1"/><rect width="7" height="9" x="14" y="12" rx="1"/><rect width="7" height="5" x="3" y="16" rx="1"/></svg>
Hi @pmario, I have no clue why I’m using H3 and I don’t have any clue what I should be using instead 
It is very interesting, thank you for pointing it out!
Hi @JanJo
I believe that switching from draggable mode to normal mode is necessary.
But maybe I can make it configurable … I’ll see
Hi all,
at the moment the dynanode widget doesn’t work as intended but I’m close to getting where I want it to be.
Tonight I’ll add an update…
Thank you,
Simon
Two line-breaks in between the paragraphs so TW will create HTML P-tags.
Hi @BurningTreeC I use icons instead of captions for the sidebartabs…with more than 6 tabs this is useful to avoid the linebreak.
I would really love to use a single column of tiddlyflex for a special sidebar (with classroomtools that would like to arrange there) but I did not succeed so far in isolating a single-column macro starting from $:/plugins/BTC/TiddlyFlex/ui/Layout , could you make such a thing possible in your plugin.
Hello all,
I have now released v0.0.151
It changes only how dynanode works
It now works applying the style contain: content to elements outside of the view
Elements with that style then are not refreshed during a refresh cycle except there are changes detected that would possibly cause such a “hidden” element to change, like if we’re editing a tiddler and another hidden tiddler transcludes that tiddler.
Performance improvements with dynanode enabled are big if there are many tiddlers open in the story rivers. The best way to feel it is opening many tiddlers for editing and dragging the sidebar resizer
I’m happy how dynanode works now and will focus on other details from now on
Thank you,
Simon
For some apps that is, I think, going to be very useful!
I did one quick test already and it is working good (50 visible, 200 not visible) with noticeable improvements.
I will test more because it is relevant to a very large project I am planning.
A dopo.

Thank you for this groundlaying work… which is so important, that it could use its own dokumentation and thread I guess.
To add my voice here as a multi-column layout enthusiast (in the general sense, currently on Muuri due to an issue with MCL):
I would say a resounding yes to being able to switch, because I often copy & paste text into other pages/software. You can only copy comfortably in normal mode, and it’s the mode I spend most of my time in.
TiddlyFlex is very impressive - unfortunately it has the same issue for me in that it doesn’t support the text preview plugin (the appear plugin is a prerequisite shipped on the same page).
I realised I was too reliant on preview and thus changed to Muuri, which is not quite as slick as either MCL or TiddlyFlex.
It would be brilliant if you could explore support for this at some point, BTC. It gets quite addictive if you lower the preview delay to 150 – 300ms!
That text preview plugin is published on top of TW V 5.1.15 (the plugin 0.5.6 / 2016-01-22 that is 10 years ago) and the genius TobiBeer has not being as active as he? once was.
Along with @EricShulman, @pmario (and notable others) especialy TobiBeer, they where all my “essential companions” when I transitioned from tiddlywiki classic V2.x to V5.x
Seems it modify the system tiddler? It have comfilct with my some other plugins, so I’m not using it anymore, and awaiting a better version of it.
@BurningTreeC Feature request! Can you pin a tiddler as a column? So if pin a layout tiddler as a column, you will get layout of layouts
Would you add the drag-drop button to the Page Toolbar, so that when the Top Toolbar is disabled, one can still use the drag-drop functionality? Same for the buttons to add and remove columns.
And on the note of toolbars, consider adding the Top Toolbar to the Toolbars, under Appearance in the ControlPanel, to make it easier for users to choose which buttons they want it to display.
