Hi
acer, try this for the file search in the panel.
Right click on the panel. Select:
Add/Remove Panel Items, select
Panel Applets, select
+Add from the right hand column. Select
Application Launch Bar and click
+Add. The newly installed
Application Launch Bar will have appeared at the bottom of the panel window below an already existing one containing the logout button. Position the launch bar in the panel using the
Up and
Down arrows in the right hand column. Click on the
Edit button in the right hand column and select,
Accessories > File Search. Click on
+Add. You should have a search icon in the panel.
I don't think the LXPanel supports just text. You can however have text and icons. Right click on the panel and select,
"Task Bar (Window List)" Settings. Uncheck the
Icons Only box and click close. That should do it. I hope this helps. Have fun

!!
