Customize or reduce length of preview text
I only have one persistent grievance with Textra, and that is the obtrusiveness/size of the preview for some URLs. This is particularly an issue when someone sends me an Instagram link. The preview often shows a wall of text filling the whole screen. Much of the information included is superfluous for preview purposes, like hashtags and likes. Typically, it's a wall of hashtags that are the biggest issue.
Textra should include the ability to reduce the size of previews (potentially by choosing the max number of text characters or lines, limiting to title text only, and/or by limiting to image preview only).
