idk if you still need this but I'm going to try to explain since somebody somewhere might! and I think I navigate it pretty well.
look at this picture, ang please ignore the anine eyes that's to blot out stuff I don't want to show. it looks like you op already understand how to make new members so ill just say to click the button with the + next to a silhouetted figure (sorta like +👤 if that imagery helps.)
first I'll explain fronting. just click the lines with an arrow near the bottom, and you should see three option.
from top to bottom, add to front (useful if someone else is already at front and you want to ad a cofronting or coconcious member), set as front (useful if you need to set only 1 alter to front, if you set as front while another alter is set as front, it will override the previous fronter and kick them off front so always use add to front for cofronting), and no action (essentially click this to put the menu down).
to use the add to front or set as front buttons, click them and they should have a ring around them, the menu will close once you do this. then find the alter you want to set/add as fronting, and click the plus/arrow button next to them.
to add a front entry, click the three lines at the very top, opposite of the magnifying glass symbol. it should take you here:
on this menu here, click the add front entry button. that will show a pop up with 2 options, again from top to bottom: add detailed front entry, add quick front entry.
on add detailed front entry, you can click specific times and dates for the start and end. they don't actually have to be exact times, usually i only use this if it was written down when the previous fronter switched in (so never lmao). these are best for longer time spans, that quick front entries dont cover. there's a button at the bottom with a shillouette of a person and a magnifying class, use that to pick the akter that was fronting for this entry
quick front entries are a bit more simple. the button to pick the fronting alter is at the top this time, and underneath are 2 sections. the first is how long ago did it end, which has options to click ranging from 2 minutes to 2 hours. click whichever is most accurate. the second section is how long did the front last, with the same options. click whichever is most accurate. you docliactually have to be exact even if it feels that way, you're just trying to get the general gist of it.
thats on fronting stuff more or less, there's more but my phone acts weird if I write long posts sooo that's where I'll leave it off. lmk if you need more help with anything!
