Tagsets on E-Hentai is a donate-only feature. This script attempts to provide some of that functionality for free.
Please see the limitations section.

Guide

Install the script and go to your watched tags on ex/ehentai. You should see a new row of buttons and a blue dropdown.

Create a tagset

1. Configure the ☑️ Watched and ☑️ Hidden checkboxes and weight values for your tags as desired
2. Click the ➕ New button and enter a name for the tagset to save it.

Load a tagset

Select a tagset from the blue dropdown, then press Save All.

Modify an existing tagset

Select a tagset from the blue dropdown and change the Watched/Hidden checkboxes as desired, then hit 💾 Save.

Remarks/Limitations

• Tagsets are stored locally in script storage, not on the server
• The script will not create or delete tags. It can only set the watched, hidden, and weight values of the visible tags.
• When browsing watched tag posts, E/Exhentai will limit the number of items shown (roughly to the last 70 days). I recommend my other script here
