Hi, i am new too, and still cry sometimes... so hard i think it is to really learn TW.... :-)
Then i see others having TW's and I scream: HOW!!!!!??? How did you do that?
So i feel you bro.
I use TW exactly like you plan to do.
For each event, thing that occurs i create a journal tiddler with date and time.
Then i use tags to tag the people involved.
I use this filter below to have overview of a day, i put the date in manually, must be possible to do that better but ok it works for me:
<$list filter="[!is[system]!tag[script]sameday:created[20210415]!tag[desc]sort[created]]">
<!-- <h2><$link>''<<currentTiddler>> ''</$link></h2> -->
<!-- <h2><$link>''<<currentTiddler>> ''</$link></h2> -->
{{!!text}}
</$list>
Hope it helps you too.
The <! comments i use to have tiddler names displayed. Twice so i can ehhhh dont know why anymore tbh :-)
Maybe this tiddler can be rebuild in some kind of matrix overview?
Other people have ideas?
Keep on TW'ing, you WILL learn!!
