I don’t know is this topic approperite in this channel.
I think tw users always search on google for icon for a certain tiddler.
Here is the tool I just found Native apps and plugins with our assets
Great thing is it has many svg icon, which I think is the best image for icon. Since when you use the icon in the tiddlymap, the image will not lose the resolution.
hopy you enjoy it 
No linux version unfortunately.
It is appropriate. But maybe you don’t know about TW Icons? It has about 47,000 icons already converted to TW specs. Best, TT.
Great site, but it is a little lag when you type in the search box. Any way to solve it?
Right. I’m not sure. Given it is just a single file TW, at it’s scale, it is pretty amazing. In practice, I think end users are only looking for a few icons and the search delay, under most systems, is (hopefully) likely tolerable.
Best, TT
Delay?, you are searching 47,000+ icons, lets keep some perspective. It appears to be a single file of 57Mb. Perhaps its load time would benefit from compression? For all I know it already does.
A local copy of the wiki will improve search speed but most I imagine will want to use such a tools for “hunt and peck”. Further, as you collect Icons that you use regularly, store them in your own local Reference Wiki.
I would like to see a conversation about identifying a larger set of highly relevant icons to tiddlywiki.
