Mozilla Thunderbird Calendar was perfect until..
Until I tried to set a task 5 minutes in size (I am logging timeboxing rather than setting things in advance) and the visual block had a minimum size that made it overlap even though the times don't (had this issue super heavily with google calendar, thought this could be the saviour but ig not). I'm not a C++/JS programmer I only know lua, html and css so I could take a look at the source code but I've also never built anything and I'm not sure if this will be as easy as tweaking a value.
If anyone has expertise and it doesn't take them that much time I would appreciate it if you could send a build where the event block can be visually any size you set it to. Thanks either way
