Hi @icelandic_crow,
Thank you for the suggestion! Regarding the background blur, we already have an enhancement in our backlog for this but it hasn’t been prioritized yet, you can find the details here.
In the meantime, I would suggest checking this post: Background blur effect, please - #3 by RenanMayrinckDesign where @RenanMayrinckDesign shared an alternative way to achieve this
As for the stroke sides, this is also planned into our backlog (you can find it here) though we do not yet have an ETA for this.
