thinking about v4 and v5, i am so glad the rendering is faster in v5 now, bc honestly how slow rendering was every time i made one small change was so awful, it was the one thing making me not use v5.... it can still be slow from time to time, but since they put out that update to improve it i definitely am thankful and use v5 way more since then.
i used to do like, all possible editting in v4 and then render out in v5 for one or two additions v5 had! but now i can do most editting in v5. i do like editing parameters in v4 more tho because of the tools, was never a fan of the node/points in v5, probably the only thing (to clarify i like the idea of the points and how to use them, but it would be nice to switch between that and the very smooth lines/no points as an option easily)
