I would like to suggest the following:
If you check a 'Include Tags into file name' option in the save dialogue, magic happens:

Frames are saved as "Filename-Frametag-Number.png"

Example:

If you have these frametags, and you set the filename as 'Monster', You would get
"Monster-Idle-01.png", "Monster-Idle-02.png", "Monster-Idle-03.png"...
"Monster-AttackA-01.png", "Monster-AttackA-02.png", "Monster-AttackA-01.png"...

This would make exporting frames really a lot easier.

Hi @hepari, actually that can be done but using the command line interface: http://www.aseprite.org/docs/cli/#filename-format

Oh thanks @dacap, but I have been trying using CLI with no luck so far. Nothing ever happens! The cli just runs without exporting anything.

This is the last code I've written up.

@set ASEPRITE="D:\Games\Steam\steamapps\common\Aseprite\aseprite.exe"
%ASEPRITE% -b EyeballB1.ase --save-as \output0\frame01.png
%ASEPRITE% -b --frame-tag "Idle" EyeballB1.ase --save-as EyeballB1-Idle01.png
%ASEPRITE% -b --frame-tag "AttackA" EyeballB1.ase --save-as EyeballB1-AttackA01.png

Could you look into this and see what I may be doing wrong? I know you have better things to do than babysit me, but I would appreciate your help very much.

Can you try:

%ASEPRITE% -b EyeballB1.ase --save-as output0\frame01.png
%ASEPRITE% -b EyeballB1.ase --filename-format "{title}-{tag}{tagframe01}.{extension}" --save-as EyeballB1.png

@dacap It worked! Thank you so much! I was about to export and rename them all by hand...

I'll be seeing this issue soon, I think some options like:

1. All frames
2. Selected frames
3. Active frame
4. Frame tag

The only problem I see with this issue is that there will be several alternatives (even more with the next v1.2-beta2 that will allow selection of non-adjacent frames), some examples:

1. Save all frames with names filename1.png, filename2.png, etc.
2. Save selected frames or frame tag with filename1.png, filename2.png, etc. or with the specific number (e.g. if we select frame 3, 6, and 9, then we would like to save filename3.png, filename6.png, filename9.png, instead of filename1.png, filename2.png, filename3.png). We can avoid this second case just for simplicity, so frames will be always saved sequentially from the first filenameN.png, to filenameN+1.png, etc.
3. Active frame should be saved with the specific given filename (or maybe we want to export just the current frame without worrying about the active frame number). So if we are in frame 3 and press "save active frame" it just update the filename3.png, and if we are in frame 5, it updates filename5.png, etc.

This will be available in the next v1.2-beta2

Has this been added yet? I'm on the newest version and don't see it. And I believe were on 1.2-beta9 or something now

Yes, it's in save copy as.

It be nice to be able to export "all" tags so that it exports all tag related stuff separately.

@Dairnon actually that's possible using the CLI:

aseprite.exe -b animations.ase --save-as animation-{tag}.gif
