With the attached javascript tiddler you can display the text-size of your tiddlers
if you want to find the larger tiddlers in your wike e.g. to reduce some of the larger imported images (images are stored in the text field)
to display the 25 non system tiddlers in your wiki sorted on size in descending order (largest first).
{{{[all[tiddlers]!is[system]textlength[]!sort[]limit[25]]}}}

* To use the filter you must first import the attached json tiddler. Drag the file $--plugin-wimmoermans-filter-textlength.js.json to the sidebare of your tw (until green import header appears) then drop, import the tiddler, save your tw, and (re)load the saved tw file.
* To uninstall the textlength filter: Open the tiddler $:/plugin/wimmoermans/filter/textlength.js then press the delete icon. press ok.
* You can also import the example tiddler list 25 largest tiddlers wimm.json.
Please note :
1) The displayed links are all in italics because there are no tiddlers present ith a name consisting of 6 digits + space + title.
Alternatively use the follwing it will display text instead of links:
<$list filter="[all[tiddlers]textlength[]!sort[]limit[25]]">
<$view field="title"/><br>
</$list>
2) To find the real tiddler, copy the name part to the (advanced)search field and click on the link from the search results.
3) The size only displays the length of text field (tiddler body), it does not include any of the other standard or custom fields.
