Hi @DavidRutten, As per the recent RCP posts, here are a couple of the most immediate points of feedback/wishes I could recall: Edit Slider Color: It’d be great to be able to edit the green accent color, as one can with groups. Set Default Slider/Group Colors: Being able to customise the default colors would also be terrific (ala Grasshopper Settings → Palette). Publish Multiple: Being able to select multiple elements on the canvas and publish them simultaneously would save a lot of right-clicks. Slider Fidelity and Lag: The RCP sliders feel slightly less responsive than their canvas counterparts, also their dragging fidelity seem less precise (this might simply be because one can’t zoom in). Slider Set Value: Being able to double-click a slider to type in a value would be great as well. Element Wishes: Gene Pool, Value List, Color Swatch, and an editable Panel. Canvas Group to RCP Group: This is a very loose idea. But something like selecting a named canvas group, iterating its elements, getting the elements that are RCP publish-able and named, and automatically making a new RCP group with these elements, might be useful (although it is definitely in Metahopper and scripting territory). Best, Anders Edit: Regarding slider fidelity, that’s probably not actually an issue, as one can simply make the RCP window wider, to achieve the same effect of increased dragging precision as one would by zooming in on a canvas slider. Never thought of that, doh: [2017-12-15 12_17_18-]

this would be the most important change.

Sliders which can be scrolled with the mouse wheel and cursor would be nice, actually not only in the remote control panel…

Specifically, the thick stroke around e.g. slider/toggle boxes and the bold font on e.g. slider/button names … A thinner box stroke and no bold fonts would be another nice tweak, if at all possible @DavidRutten Bump on this one. I’m guessing there won’t be a native RCP replacement for a while (if ever). So any small edits you can make to the current one would be much appreciated. Cheers. TLDR: Drop bold fonts + make all borders 1 pixel wide :folded_hands:

[image] Remote Control Panel (RCP) - Wishes and Feedback Grasshopper2 I’ve been updating a definition for Rhino 8 that uses the RCP quite extensively. And while the tweaks to colors are much appreciated (e.g. sliders/toggles don’t look disabled), our industrial designers and myself find that certain RCP elements look a wee bit overly “bombastic”. Specifically, the thick stroke around e.g. slider/toggle boxes and the bold font on e.g. slider/button names: [2025-09-23 08_15_34-Greenshot] A thinner box stroke and no bold fonts would be another nice tweak, if… Double bump on this one :backhand_index_pointing_up: Again, TLDR: [image] AndersDeleuran: Drop bold fonts + make all borders 1 pixel wide :folded_hands: Also, it would be great to hear if there are ANY plans to continue native development on the Grasshopper 1 RCP (e.g. adding Gene Pool, Value List, Color Swatch, and an editable Panel, see first post from 2017)? And if Grasshopper 2 will eventually get an RCP? It’s been well over a decade with plenty of more or less usable third party Grasshopper GUI plugins, but I really much prefer native McNeel solutions (that doesn’t require me writing tons of e.g. ETO code, assuming that’s the only alternative currently) :old_man: Edit: Ping @DavidRutten

Anders, do you have a small version of one of you RCP controlled scripts? I would be happy to spend an hour or two to re-write this using DKUI - which allows for full control of the style via CSS. I would just ask that I be allowed to make and publish a video of the process as an example. Please let me know if this would be of interest? Cheers Dk

I don’t use third party plugins/dependencies, unless strictly necessary. But thanks so much for the offer :slight_smile:

[image] AndersDeleuran: And if Grasshopper 2 will eventually get an RCP? Eventually. It’s a big job and as GH1 showed, a lot of really bad decisions can be made in a short span of time. It’s currently not on the 9.0 stop ship list, so this will appear some indeterminate time after first Rhino9 ships, but it will be part of Rhino9 development.

That’s great news, thanks for clarifying this. Really looking forward to seeing what you come up with! We’re probably quite a few years away from using GH2 in production (especially one with an RCP). So if at all possible, myself (and I think many users) would benefit greatly from just adding the Value List to the existing Grasshopper 1 RCP. Having drop-downs and check lists would improve things significantly. Anything else is just gravy, but of course styling also matters :artist:

Fair enough @AndersDeleuran. Though I would note that with the installation of DKUI - and many other 3rd-party plugins - now being 100% taken care of by the Rhino Package Manager, it’s MUCH less hassle than dealing with plugins in the past. Having a rich and well-supported ecosystem of plugins, and opening your workflow up to the work of developers beyond just the McNeel team, is honestly one of the huge advantages of design and development in Rhino. Cheers, DK
