agreed on all points; I will suggest zotero for you tho, which will let you organize pics and charts so they are there when you need them

• another point is that I have not had a problem with going back to an old steemit article and re-doing it...I try to keep it outside of a 6 month window at the least, but it's one way to update a "draft" with pics and incorporate the useful comments folks leave
