Well not for a user. But …
40 minute snapshot of memory utilization shows starting at 105/125 mb for the JavaScript VM (webflow) then to 462/604 MB. This was on a clean instance of Chrome Developer , one tab only. Total 1,745 MB memory used for Chrome on this instance. Basic use. No uploads. Just CSS edits.
@webflow - so there looks to be a potential issue with memory utilization of the webflow JS VM.
