Hi ReX, it sure has been a long time. Glad to see you here.
1. Yes, it does. I added this in V1.15. There's also a Find It button, which I think is pretty cool. It will search for the specific file, but it will prefer to go into folders named like "DOOM" or "GAMES" first, so it's somewhat likely to find the files faster.
2. It does show the name of the WAD you open in the status bar (new in V1.15), but adding it to the title bar will be done.
3. Thanks for noticing!
4. You can't copy between two instances of XWE, in fact if you have two separate instances open, things may get messy. I'll work on this issue later. But copying lumps between files is easy.
- open your source WAD, select the entries you want and click COPY.
- If you have more entries you want to add to the clipboard, just keep clicking copy, and it will NOT clear the previously selected entries, but rather add to them. (Also, open up your temp folder - by default, it's c:\windows\temp and you will see what XWE does with these lumps.) Note: there's a new option since V1.14 that disables the 'multiple copy' behavior, but it's not turned on by default.
- Once you've selected all the lumps, just open up the destination WAD, go to the place you want to paste them, and click PASTE.
When the entries are copy/pasted this way, the order of them will be retained. (If you looked at the the temp folder, you'll see why.) This is not only fast and easy (vs. saving the lumps separately), but it will also avoid all the problems you mentioned in step 5.
5. Saving the individual lumps of a MAP is just not the right way. If you do it with one map, it won't be TOO messy, but it's the Windows Open dialog that will sort the names - and therefore mess up the order. If you try this with two or more maps, that will just be a disaster. Like you said, you'd have to arrange them back in order and figure out which lump belongs to what map. Just do copy/paste instead, as described in 4.
6. It's not disabled, it's still there when you open a map. That function lists USED textures.
The menu item you mention is a newly added and incomplete feature, I mentioned it here: http://www.doomworld.com/vb/showthr...ures#post494083 In this version I left it in, but it doesn't do much yet. It creates a file (C:\not_used.txt) with the textures that are NOT used in any map. This function is pretty complex to write, because a lot of lumps have to be processed in order to properly determine whether a particular texture is actually used. (E.g. a sky texture could be mentioned only in the MAPINFO lump, or new animations can be created, etc.)
Right now, if you don't use any "fancy" things, just regular doom maps, then you can use that text file to check whether there are any custom textures you've loaded that are not used. I'll keep working on this feature though.
