This idea is meant more as "guidance/something to think about," as I know MEUE is in the middle of development, and I want to ensure this detail is not missed.
Today, when you use the Marketo UI, users are allowed to enter content into areas such as filters or flow steps despite there being practical limits on the amount of content Marketo itself can process. A common example of this would be filter criteria in Smart Lists--I've been asked many times over the years to pull lists of specific email addresses, and there are practical limits on the total length of text that can be listed inside a certain filter (roughly 2KB). Likewise, this also appears in other contexts--Send Alert seems to have a practical limit of 2KB' worth of email addresses, but the UI does not enforce this limit.
This results in confusion when these steps fail or do not work as expected.
As areas of Marketo Engage continue to be redesigned, can maxlength attributes be set on these sorts of input areas to reflect what the platform can handle accurately?
