Editable Value fields on Editor canvas to increase in scale when view is zoomed in beyond actual size.

Sometimes I zoom in to read the small expressions in Calculate nodes, especially at night time. While the expression in the canvas is enlarged as you zoom in (but truncated), if you double click the field to edit it, the text is still the small size as per an "actual size" zoom magnification. SO it's still hard to read on a big screen for me at night a fair distance from my eyes.

As illustrated below.

Console window, is there a way to switch it off?

I want to include some debugging features in a sub-comp, but to have a switch on the Display Console Window. It seems like the window will be displayed on the existence of the node(s) even if no event or data ever reaches the node? I'll turn this observation into a FR if my assumption is correct. Thanks.

Thanks Jaymie Vuo 1.3 is going to be a mammoth release by the looks of it.

Please consider 'macros' or Group Nodes as a high priority for composition tidiness, and I suspect for Editor run time performance too? To my way of coding it's as important for legibility and coder comfort level as the canvas notes (which will be coming in 1.3 I believe, exciting!).

On the Modules folder, would all Vuo compositions in any given folder share access to the Modules folder? In one sense this is a feature (shared non-global scoping of sub-comps) in another way it's a kinda a potential liability: each Vuo comp (including version saves which is how many of us save our work) with sub-comps would require its own parent folder to maintain single Vuo file scope for the sub compositions.

Team Vuo have probably thought it all through better than me, but that did occur to me as a potential issue. I guess it's better than embedding the sub-comp file in the Vuo file though which was how I kinda assumed it would work.

This composition is a bit more complex, but it uses position (in polar co-ordinates), velocity and acceleration to move an autonomous car around a track. It just uses Hold Values and calculations to do the maths, most of the other nodes (grey) are additional stuff for screen printing data and converting the polar coordinates to cartesian coordinates. Unfortunately we can't hide them away in macros just yet.

Look for the "tangerine" coloured nodes, they do all the work and there's only three holds and three calculate nodes one of each for each variable (position (θ), Velocity and Acceleration).

You'll need to relink to this image for the car. Or just substitute with a Vuo circle node.

You should be able to get by with just a Hold Value or Hold List node, don't need Select Latest, Changed, Spin Off Event nodes in normal circumstances. The Hold node allows you to do the update on a value using its own contents in the calculation. Typically the update event going to the Hold node (allowing it to update itself) comes from a Build List or Fire Periodically node.

Will have a look at your comps when I get a chance. We're in the same boat I think :-)
