You assume, that everyone knows how TidGi Desktop UI looks like. I have never seen a screenshot here at Talk. I could find one at: TidGi Github page.
If that’s the start UI. I’d say: Yes there are too many buttons and the font is not “my taste”.
There is a reason, why tiddlywiki.com initially only offers 3 buttons (now 4 with the experimental interactive tutorial). Most humans can deal best (only) with 3 elements at the same time.
We do have requests, to simplify the layout even more for default users. … But I personally be the wrong user to decide it.
The first thing I do with a TW site, is add my own plugins, that do not need a restart, from the browser bookmarks bar.
So after a view seconds tw-com looks like this:
Any other TW page, that I open may get the same treatment, if it allows it.
If UI elements are hidden, but I want to see how it’s done, I download the wiki, open the browser dev-console and switch stuff back on – if possible.
So I am not the right one to decide, what a minimal UI should look like. – I only know, the the “hamburger icon” is the worst thing that happened lately.
